2017+ Mazda CX-5 Turbo Lowering Springs are Here!

We are proud to announce the Sport Lowering Springs for 2017+ Mazda CX-5 equipped with the 2.5L turbocharged engine. We took a fresh approach to spring design to offer you the best combination of style, ride quality, and handling in a package that fits just like OEM. The new Mazda CX-5 looks great, but a functional drop gives it just what it needs to look even better.

Let’s get right to the point…ride height. The CX-5 looks great but it needs a drop and dropped it we did. Being an SUV, the factory ride height is pretty high up so we were able to make a significant drop while still keeping your SUV functional and practical for a daily driver.  

These springs offer a drop of about 2.1 inches front & rear. We chose this height as it offers a great new look without sacrificing any of the daily drivability of the Mazda CX-5. This height clears the typical driveway with no issues, and retains plenty of suspension travel, even when fully loaded with 5 adults and weight in the trunk. 

Driver + Rear Passenger

The height drop will be noticed when you’re outside the car, but the handling improvements will be apparent when driving. By lowering the center of gravity and stiffening the springs, body roll is reduced in corners, giving you extra confidence when attacking that backroad (Haha we know it’s an SUV). Also, we stiffened the rear springs more than the fronts, reducing understeer. By number, this meant 3.4K front springs (17% stiffer than OEM) and 7.0K rear springs (32% stiffer than OEM). 

CorkSport

While this may sound like a big jump, they ride very similar to the OEM springs. We used natural frequency analysis and referenced our spring designs from earlier CX5 models to ensure we achieved comfortable characteristics over bumps. The spring rates we chose fit well with the stock shocks and struts to prevent any bounciness, plus, the drop ensures you are in the normal operating range of the dampers. This means no prematurely worn shocks/struts due to springs that are too low.

Lastly, the CS Sport Lowering Springs are made from high tensile strength spring steel and come with pre-installed spring isolators to eliminate any unwanted noises common with lowering springs. With that, we are introducing our new CorkSport Blue powder coat for long-lasting quality and corrosion resistance. They install just like stock, reusing all your OEM components. The only permanent modification is trimming the bump stops to match OEM suspension travel.

4th GEN Mazda 3 SRI

4th Gen Mazda 3 Power

We are proud to announce our first product specifically for the 4th GEN (2019+) Mazda 3: the CorkSport Short Ram Intake. Gain horsepower, torque, and some much needed sound from your 2.5L SkyActiv-G in only about 30 short minutes. Features include an AEM dry-flow filter, a billet machined MAF housing, a custom designed reinforced silicone coupler, and stainless steel T-bolt clamps that combine to be a great and simple upgrade for your new MZ3. Read on for more details!

Increase horsepower in your 2019+ Mazda 3 with the easy to install Intake
CS Short Ram Intake

We’ll admit this intake has been a bit of a challenge since Mazda has switched to a new style of MAF sensor that is very sensitive to changing the intake. We’re happy to report that we’ve figured everything out and have had 5 cars successfully testing the intake for hundreds of miles with no issues. Now, onto the fun stuff!

Let’s jump right into the fun stuff: power! By removing the restrictive factory intake and filter, and replacing them with the CorkSport SRI, we were able to pick up 5-7WHP and 5-7WTQ when tested back to back on our dyno. This was tested within an hour or so of each other, with no tuning changes, and with the only change being the intake swap. Check out the dynograph down below! For both intakes, the only other mod on the test car was a prototype CS axle back exhaust (coming soon!). This will not affect power gain from the intake as it was installed for both tests.

Power is not the only benefit though. The CS short ram intake offers a great visual boost to your engine bay. You can even personalize your intake as you can select between red, blue, and black silicone and filter as well as polished or black clamps. Appearance is not even the best part-the CorkSport intake adds some much needed growl to the engine to give some more excitement when you get on the gas. It’s not obnoxious, but noticeable and definitely enjoyable.

To make the power and great noise, each component in the CS SRI has been optimized for performance. Starting at the filter, an AEM Dry-Flow is used for fantastic air flow capacity without compromising filtration. A non-oiled filter is used specifically to prevent issues with the MAF sensor.

Next comes the billet MAF housing. We use a precision machined MAF sensor housing to ensure the diameter of the intake near the MAF sensor is an exact match to the OEM diameter. This keeps fuel trims in check and keeps the check engine light off. A billet MAF housing has the added benefit of looking great, especially when finished off with an attractive laser etched logo.

We have 3 color options available for the 2019+ Mazda 3 intake

The MAF housing connects to the throttle body with a custom designed and reinforced silicone coupler. It is a perfect fit with the OEM throttle body and valve cover vent hose while the four layers of nylon braiding keep the silicone strong for years to come. This piece of silicone has the added benefit of being completely smooth on the inside versus the accordion OEM rubber piece. This helps promote flow into your engine.

Finally, all of the components are tied together with stainless steel T-bolt clamps. These clamps offer superior sealing characteristics over a traditional worm gear clamp and are not prone to stripping like a worm gear clamp.

The CorkSport GEN4 Mazda 3 Short Ram Intake is finally here and it’s a great upgrade to start getting your 2019+ 3 to perform as good as it looks. Be sure to check out the product listing and video and don’t hesitate to give us a call with any questions!

Skyactiv 2.5T Intake Heat Shield

OEM Look and solid performance power gains for the Mazda 6 Turbo

We’re back with another product for SkyActiv 2.5T owners that a lot of you have requested after getting your CorkSport SRI. Introducing the CorkSport Heat Shield for 2018+ Mazda 6 Turbo, 2019+ Mazda CX-5 Turbo, and 2016+ Mazda CX-9! Cool down your intake air temps in two ways: by blocking heat from the engine bay and by using the OEM ducting to draw in fresh air. This allows your turbo system to breathe just a bit easier, especially during hot days or if you’re stuck sitting in traffic. Plus, it makes the CS SRI look like a factory option performance part!

Read on for full details and be sure to give us a call if you have any questions!

Isolates heat from the Mazda 6 turbo SRI

We really focused on keeping cool air around the filter with the CorkSport SkyActiv 2.5T heat shield. The shield was carefully designed to seal the intake off from as much engine bay heat as possible. This meant a complicated 2 piece design that is riveted together. We also designed the shield to work with the OEM air ducting. This directs cool outside air to the filter, further reducing intake air temps. The shield is also left open to the area in front of the tire, underneath the headlight. We found that this area gets some fresh air during driving as well, further keeping air temps down.

Now what benefits does cooler air offer? The basic generalization is that since cooler air is denser than warmer air, your engine can ingest more air per cycle, and make more power. When a car is turbocharged though, this gets a little more complicated as you have a turbo that compresses and heats up your intake air and then an intercooler that cools down the boosted air before even getting to the engine. What that means is that the “colder air will make more power” generalization may not hold true, especially with how advanced modern turbocharged vehicles have become. What colder intake air does offer you is a less stress on your turbo system. Colder air means your turbo does not have to work as hard to flow the same amount of air at the same boost pressure. In addition, colder intake air can translate to slightly cooler air exiting your turbo and heading to your intercooler, taking some stress off the intercooler as well.

Enough theory, let’s talk results! In both daily driving testing and in torture testing on the dyno, we found decreased intake air temps with the CorkSport Heat Shield installed. When cruising or when it’s cold outside, we were actually surprised at the low intake temps of the CS SRI alone—there’s actually a surprising amount of fresh air that gets into the engine bay. Where the heat shield really comes into its own is when sitting stationary or driving on a very hot day. That’s when we saw our biggest improvements in intake air temp.

While we did not see any notable changes to horsepower, our torture testing on the dyno really shows what a worst case scenario would look like for intake temps. Check out the graph below that compares the CS SRI alone vs. the CS SRI and heat shield combo. This is a little exaggerated due to decreased airflow on the dyno but is similar to what your engine could see when sitting in traffic on a hot day, then accelerating back up to speed.

The CorkSport Heat Shield is made from laser cut and precision formed carbon steel. We chose carbon steel for great strength and lower heat transfer than aluminum. For corrosion resistance, the heat shield is finished off with wrinkle black powdercoating. This coating also gives the heatshield a great look that helps it blend in with the rest of the engine bay and make the intake system look like a factory performance part! The two sections of the shield are attached together using stainless steel rivets for a great look and long lasting strength. Lastly we include rubber edge seal to keep as much heat out as possible, and to prevent any vibration or unwanted noise.

4th Gen Mazda 3 Sport Springs

The 2019+ 4th generation Mazda 3 is a car that certainly divided opinions when it came out. From its divisive looks to the new torsion beam suspension, even we weren’t quite sure what to make of it at first. However, we have since fallen in love with our shop 4th GEN, a big part of it is what we are releasing today: the CorkSport Performance Lowering Springs for 2019+ Mazda 3 (Sedan & Hatchback for both AWD & FWD). Give your new 3 an aggressive look that is sure to turn heads while improving the handling for those twisty backroads!

2019-2020 Mazda 3 lowering springs
Gen 4 Lowering Springs

Let’s start off with the elephant in the room: ride height. When we developed these springs, it was somewhat difficult as we had to account for different body styles, transmission options, and now even driveline options. With all things taken into account, we found the right range of ride height that looks great on the lightest, heaviest, and all options in between.

The perfect balance of lowering for the 2020 Mazda 3
Why Lowering Springs?

On the lightest GEN4: hatchback, front-wheel drive, manual trans, the CS lowering springs offer 1.5” front and 1.8” rear ride height drop. On the heaviest GEN4: sedan, all-wheel drive, auto trans, the CS lowering springs offer 1.6” front and 2.2” rear ride height drop. Depending on your vehicle’s options, you will end up at or between these extremes. Don’t worry though, your ride ends up sitting level no matter what combination of options you have. The images below show the lightest (upper) and heaviest (lower) Mazda 3.

We also focused heavily on improving the handling with the CS GEN4 lowering springs. A lower ride height means a lower center of gravity which when combined with a stiffer spring rate, means less body roll. This improves handling feel and driver confidence when attacking a backroad. We even increased the rear spring rate more than the front to reduce understeer and help with turn-in.

All Lowering Springs

The CorkSport 2019+ MZ3 springs went through a few different iterations of spring rate and ride height before we found the best balance of ride quality, handling, and appearance. The final spring rates are 3.4K front and 5.9K rear. Compared to the OEM rates of 2.23K front, 4.20K rear, we made a decent jump in rate; however, the new springs are well within the OEM damping rates. The ride is obviously stiffer than OEM yet is not bouncy and you can still comfortably daily drive on the springs.

The perfect lowered stance for your 4th Gen Mazda3
CorkSport

During development, we even tested for the natural frequency changes in the suspension from installing lowering springs. Essentially, the natural frequency is a good way to compare how “stiff” one car feels compared to another, even if their suspensions are different (for more background info on natural frequency, check out this blog). We went from an OEM of ~1.6Hz front and rear to 1.75Hz front and 1.8Hz rear on the CS lowering springs. This increase is enough to feel “sporty” but not enough that it will ruin your drive to work.

FWD or AWD the springs work on all 2020 MZ3
Gen 4 Springs

As with all CS lowering springs, they are a direct fit install that can completely change your car in only a few hours. The only permanent modifications are trimming the OEM bump stops to account for the lower ride height. To ensure they will last as long as your car, each spring is made out of high tensile strength spring steel, which is then powder coated blue for corrosion resistance and a great look. The rear springs even include spring silencers to prevent any added noise from the lowering springs.

The CorkSport GEN4 Mazda 3 Lowering Springs have really changed our opinion on the new body style. With the right set of wheels, our CS shop car turns heads all day long and would fit right in at any car show. If you’re ready to upgrade your 3’s handling and give it an aggressive look, we are happy to help!

Performance Parts for the SkyActiv-G Turbo 2.5L

About a year and a half ago we launched our first performance part for the highly anticipated turbocharger 2.5L SkyActiv-G; the Short Ram Intake. This being the first factory turbocharged engine in a Mazda since the long-missed Mazdaspeed 3 in 2013. We were eager to start developing new and exciting products for the Turbo SkyActiv…and trust me that passion has not slowed down.

Today we are going to give you a sneak peek of what’s to come for the Sky Turbo 2.5L through 2020.

2018+ Mazda 6 Turbo 2.5L – Sport Lowering Springs

First up is not necessarily a new product for your Mazda 6, but is an iteration in response to the feedback we’ve received. The current CorkSport Sport Lowering Springs for the 2018+ Mazda 6 (shown above) are sporty, comfortable, and provide a balanced drop of 1.0” Front and 0.75” Rear. While many have praised the springs in their current iteration, some have asked for a more aggressive feel and stance.

We’ve heard you and we are taking action. We are currently developing more aggressive sport springs that will drop the ride height further and bump up the springs rates a bit; we are calling these the “LowLow” springs. Since we are still in development we have not finalized the ride heights and springs rates, but we have a target drop of approximately 1.5” Front and 1.65” Rear.

2018+ Mazda 6 Turbo 2.5L Short Ram Intake

Next up is a new product and one that many of you are asking for. While the Short Ram Intake does increase performance and looks great riding solo in the engine bay, we’ve decided to develop a heat shield kit to further compliment the SRI. We are in the final testing and validation stages, seeing great results with cooler intake air temperatures.

We will be launching the heat shield kit as a solo option so you can upgrade your current SRI system and in a bundle deal if you are looking for a complete kit for your Turbocharged Mazda 6, CX-5 or CX-9.

CorkSport

Next up is a completely new option for the SkyActiv turbo platform…high-performance turbo inlet pipe. This is the first turbo inlet pipe option and is designed to install with the OEM battery, but why is this important or exciting? Just like the Short Ram Intake, improvements inflow in and out of the engine increase efficiency and thus overall power potential.

Turbo inlet pipes are a common upgrade for the Mazdaspeed platform as performance requirements increase. While most of those turbo inlet pipes are manufactured from aluminum pipe or silicone, the SkyActiv-G Turbo Inlet Pipe will be manufactured from cast aluminum. This allowed us to maximize space with a unique shape and still maintain OEM like fitment. Stay tuned for more info on this project.

Did you notice that there is a blue and red silicone coupler on the intake system? In the very near future, we will be providing silicone color options for the Short Ram Intake: Black, Red, Blue so you can choose a style that fits your car best.

CorkSport

Lastly is the other side of the engine. To complement the CorkSport 80mm Cat-Back Exhaust, we are developing a High-Performance Downpipe in two setups. Race Only Non-Catted and Street Catted setups.

A first for CorkSport, we are designing the downpipe in a “modular” design that will drastically reduce the difficulty in installation and improve durability. The upper section directly bolted to the turbocharger is a cast 304 stainless steel with included heat shield and the lower section is thick-walled 80mm stainless steel piping. They connect via a v-band clamp for a simple install process vs wrestling the entire downpipe into the car and onto the turbo.

Wow, that was a lot, and trust me there is more we are investigating, but we can’t let ALL the secrets out yet. We would love to know what products you would like CorkSport to develop for the 2018+ Mazda 6 SkyActiv Turbo platform, you can do so right here by Submitting a Product Idea.

Thanks for tuning in with CorkSport. We hope you are as excited about the 4th Gen SkyActiv Turbo platform as we are!
