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.

The Best Power Mod For A Mazda

In the ongoing quest to make your Mazda more powerful, and fun to drive, we have developed many great aftermarket options.

The stock airbox and air intake on most Mazdas were designed for economy instead of power. The problem with using the stock filter and airbox is that it functions similar to breathing through a rag. The rag does a great job of keeping contaminants and dirt out, but it also requires extra effort to pull air in.

When you upgrade the intake to a CorkSport Short Ram Intake you remove the air stifling setup and finally breath freely. Suddenly, your car goes from an underpowered, oxygen lacking zombie, to the free breathing, throaty roar of increased horsepower and freedom.

Take a look at a section from our book “The Ultimate Mazda Performance Guide” about how a Short Ram intake system should be your first modification for power.

If you are looking to start the year off right, and are ready to upgrade your intake system we can answer any questions on which option is best for your ride.

Want to start 2014 off with some extra power? How about just letting your Mazda breathe easy? Thankfully you can do both with one simple modification, the Short Ram Intake.

A Cold Air Intake is one of the easiest ways to gain consistent power in your Mazda. With the CorkSport Power Series Cold Air Intake for your 2010-2013 Mazda 3 you will pull cold air directly into your engine which equals more power at your wheels. In testing the CorkSport Power Series Cold Air Intake proved to give peak gains of almost +6hp and +6lb/ft of torque.

CAI versus stock 25 mazda3

Not only does the Cold Air Intake increase power, but it will improve efficiency and consistency by giving your engine colder air which is better for combustion. The CorkSport Power Series Cold Air Intake provides the benefit of pulling the denser, colder air from outside the engine compartment.

We designed the Cold Air Intake for both the 2.0L Non SkyActiv models, along with the 2.5L Non SkyActiv model. With more power and efficiency across the board we decided to let everyone in on the performance gains.

Made of a polished, mandrel bent aluminum pipe, with durable multi-layer, reinforced silicone couplers and our one piece precision machined and anodized aluminum MAF housing, the CorkSport Mazda 3 Power series Cold Air Intake will be durable and look great. We also include a Dry Flow Air Filter that is easy to clean and never needs replacing.

CorkSport September Featured Car of the Month: Brandon Graser

Brandon-CorkSport-Car-Of-September-Mazdaspeed-Mazda

Brandon found himself looking for a new car, and in the price range that he had at the time, he test drove quite a few. He was hooked on the fact that the Speed 3 was the “best bang for your buck and the most fun to drive”. He enjoyed the overall look, style, a feel of the car; “this one” was the one to get.

CorkSport-Mazdaspeed-3-Eyelid-Headlight-Cover

Every car he had ever modded started with an intake and since “CorkSport was right here in town, just a couple miles away” it seemed like the most realistic option for him to check out what we had to offer. He can’t quite recall whether or not he purchased the CORKSPORT Stage II Power Series Short Ram Intake for Mazdaspeed 3 by itself or if he walked away with a lot more that day after talking with Austin. (Our records show he definitely did: CORKSPORT 2010+ Mazdaspeed 3 Cat Back Exhaust, CORKSPORT Urethane Exhaust Hangers, CORKSPORT Mazdaspeed 3 Downpipe).

He does know that he definitely went on a binge and found himself at CorkSport quite often. Of course, he found himself working on his car even more. CORKSPORT Underhood LED Light KitCorkSport-Featured-Car-Of-The-Month-Brandon-MS3-Underhood-LED-Kit

He’s never been to a show, nor has he entered a contest, so let’s just say he’s batting 1000 at this point, after winning the CorkSport Featured Car of the Month with his extensive submission and CS plastered Mod list.

AMO, (Awesome Mazda the Original) as his one of his lady friends has christened it, is something that he’s pretty proud of. “I’ve done most of the work myself with the help of some friends, and all of it with very little previous DIY experience.”

CorkSport-Featured-Car-Of-The-Month-Brandon-MS3-Speed3

When asked what his “favorite” mod was thus far, he said, “The most significant difference in the car is how it sounds now, after the cat-back exhaust and the downpipe were put in.” CORKSPORT 2010+ Mazdaspeed 3 Cat Back Exhaust, CORKSPORT Mazdaspeed 3 Downpipe.

Next on the list for upgrades will be some lowering springs or coil overs. “The car pretty much looks stock at this point. You can’t tell how much work has really been put into it, because I’ve left the styling alone except for the eyelids and array of stickers of course. It’s a “NEED” to make it look better, and the improved handling will just be a plus.” CORKSPORT Mazdaspeed 3 Lowering Spring Set, CORKSPORT Coilover Suspension Kit Mazdaspeed 3/Mazda 3

Brandon doesn’t find himself alone in the car that often. Remo, his full breed miniature long haired dachshund, is normally right there in the shotgun seat being a perfect copilot. “He’s an old quirky little guy, but always up for a drive.” You can find Brandon and Remo around the Vancouver, WA area, headed to and from work or taking the occasional drive out to Sunset Falls. “It’s in the middle of nowhere, with zero traffic, lots of twists and turns and of course the privacy to drive a ‘bit’ faster.”
