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 is 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.

Mazda 6 Turbo Car — 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, and 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 spring rates a bit; we are calling these the “LowLow” springs. Since we are still in development we have not finalized the ride heights and spring rates, but we have a target drop of approximately 1.5” Front and 1.65” Rear.

Mazda 6 Short Ram Intake — 2018+ Mazda 6 Turbo 2.5L Short Ram Intake

Performance 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.

Performance Turbo Inlet Pipe

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 in airflow both 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.

Mazda Performance Downpipe

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.

Stay Up-to-date with CorkSport

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!

We have love for the Cx5 Turbo

With the success of the CorkSport CX-9 axle back, it was time to turn our attention to the slightly smaller little brother, the CX-5. We are proud to introduce the CorkSport 80mm Axle Back Exhaust for the 2017+ Mazda CX-5 equipped with the 2.5T. If you’re looking for a little more life out of your new CX-5 Turbo, read on for full details on how to give your grocery-getter some growl.

With our experience with the SkyActiv 2.5T in the CX-9 and Mazda 6 exhaust, we had a pretty good idea of the correct balance of volume and tone that would be a good fit for the CX5-T exhaust. With this, we ended up with 80mm, mandrel bent piping that feeds through two large flow-through resonators. The large resonators keep the noise and drone down during regular driving yet the larger piping size and flow-through design of the resonators ensures you can actually hear your 2.5T when you get on the gas. It’s a throaty and deep sound that adds some much-needed excitement to the CX-5. It’s not all sound though, the larger piping and flow-through resonators are much less restrictive than the OEM muffler section. While we haven’t had a chance to get a CX-5 on the dyno, the 2.5T is definitely breathing easier.

Aside from the obvious sound benefit, the CS axle back adds a visual boost that looks at home on the rear of the CX-5. The exhaust tips were enlarged to 100mm to fill in the bumper cutouts. They were also extended outward slightly, and a slant cut was added to the end. This gives a stylish and classy look that should’ve been the way Mazda made it! The tips are garnished with a laser-engraved CorkSport name badge for a nice finishing touch.

Tig Welded Mazda Cx5 2.5T Axle Back Exhaust

The entire CorkSport axle back exhaust is made from fully polished 304 stainless steel that is precision TIG welded together. This construction ensures good corrosion resistance and strength to last as long as you own your CX-5. Plus, being fully polished, it looks great if you ever catch a glimpse past the tips. In addition, we supply the hardware and gaskets you need for installation, so spicing up your CX-5 can be done in as little as 30 minutes!

Want to hear the Cx5 Turbo Exhaust? Check out the Youtube Vid below.

CX5 Turbo Performance Dual Axle Back Exhaust

There you have it, the new CorkSport 80mm Axle Back for 2017+ Mazda CX-5 2.5T. Be sure to visit HERE for sound clips and video of the exhaust on car!

For all you 2017+ non turbo CX-5 owners, yes this will fit your Cx5. The exhaust note of the axle back will be different without the turbo in the system and will be comparable to our 1st Gen Cx5 axle back.

If you’re still curious, give us a call and we can answer any question you may have!

Oil Catch Can Kit for 2016+ SkyActiv Turbo 2.5L

When you think of a performance aftermarket component you typically think of a part that increases the vehicle’s power, but some performance parts don’t. Instead, they have a more critical purpose, increasing the reliability of your performance engine and components. The CorkSport Oil Catch Can Kit (OCC Kit) is just that type of component(s).

Why is an Oil Catch Can Kit critical for your Mazda? Despite the huge advancement Gasoline Direct Injection (GDI) technology there are still some downfalls. Compared to the more conventional port injection fuel systems, GDI is much more prone to engine oil fuel dilution. This is primarily due GDI injecting directly into the cylinder; in low speed operation and cold starts the fuel simply does not have enough time to fully atomize into a gas before ignition. This results in some excess fuel seeping past the piston rings into the oil along with any combustion chamber blow by the pistons. This is fuel dilution.

OCC catch all the nasty build up from entering your Mazda Skyactiv engine

Here you can see the results of a CorkSport OCC installed for ~3000 miles on a 2018 Mazda 6 2.5T. This engine only has 500 miles and has an average commute of 15 miles & 20 minutes of mixed traffic and speeds.

Mazda’s OE design attempts to resolve some of this with a valve cover breather that vents directly into the turbocharger compressor inlet and a PCV (Positive Crankcase Ventilation) valve in the engine block that vents to the intake manifold.

Mazda’s setup depends on the fuel and water vapor inside the crankcase being drawn into the intake manifold and intake system to then be re-ingested by the engine. This has two major flaws:

The direct crankcase ventilation via the PCV valve only works while cruising (no boost). Combustion gas blow by will occur most often while in boost under high throttle application when the PCV valve is closed.
This forces the engine to re-ingest dirty air that carries contaminants in the form of fuel and water vapor along with carbon debris. These containments then build up on the inside of the intake manifold, cylinder head runners, and the intake valves slowly degrading performance over time.

Carbon build up on a Mazda engine without the catch can

The CorkSport OCC Kit provides you with two major features:

Both the valve cover vent and the PCV valve are drawn from the turbo inlet directly ahead of the turbocharger compressor. Thus both the valve cover and PCV valve have constant vacuum in all driving conditions, both cruising and high throttle application.
The oil catch can itself acts as a “filter” for the vapor and debris that would normally be directly ingested by the engine. The drawn crankcase vapor and debris is separates and collects in the catch can for easy removal during normal oil changes.

As you saw above, there is a significant amount of vapor and fine debris that is being filtered out of the crankcase air that would have normally been ingested. As you continue down the path of modifying and demanding more form your Mazda, the need for a OCC System only becomes more and more critical.
