Introducing the CorkSport Heat Shield for Mazdas equipped with the 2.5T engine. Get some cooler intake air for your Mazda 6 Turbo, CX-5 Turbo, or CX-9 by blocking the heat from the engine, and drawing fresh air in with the OEM ducting and fender well. This lowers stress on your turbo system so you can keep making power, no matter the outside temperature! Whether you’re upgrading your existing CorkSport Short Ram Intake, or are getting the whole package at once, the CorkSport heat shield is a great mod to compliment your build.
Temperature Focused:
The CorkSport Heat Shield for SkyActiv 2.5T reduces intake air temp in two ways: by blocking heat and by directing cool air in. We carefully designed the shield to seal off the intake from as much engine bay heat as possible. Then, the OEM air ducting is retained to feed cool outside air to the filter along with an open path for cooler fender well air to enter, resulting reduced intake air temps. While not as crucial on turbocharged cars, the lower intake air temps means your turbo and intercooler do not have to work as hard to make the same power on hot summer days! For more info on why this is true, check out our blog for this product!
Testing and Validation:
We went through extensive testing to ensure that the CS heat shield functions exactly as intended. Through both daily driving and torture testing on the dyno, the CorkSport Heat Shield showed decreased intake air temps. While we did not see any definite power gains, your engine and turbo system won’t be working nearly as hard to make that power. Check out the image to the right to see a comparison of intake air temps between the CS SRI only vs. the CS SRI & Heat Shield under the same conditions. This is a little exaggerated due to the decreased airflow when 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.
Materials & Manufacturing:
The CorkSport SRI Heat Shield is made from laser cut and precision formed carbon steel. This ensures good strength and low heat transfer through the material. The upper and lower sections are riveted together using stainless steel rivets for a great look and strong shield. We finish it off with a wrinkle black powdercoat that really makes the heat shield blend into the engine bay and look like a factory performance part. We also include rubber edge seal to help keep heat out and prevent any vibration noises.
