The CorkSport Heat Shield is a great addition to the already fantastic CS Short Ram Intake that we offer for the Mazda 3 Turbo and CX-30 Turbo. The CS Heat Shield helps block out unwanted heat that comes from the radiator, engine and transmission providing the CS SRI with fresh air. The barrier reduces heat soak while stationary and helps funnel cooler ambient air to the intake faster once driving. The CS Heat Shield is a great mod if you want to elevate the performance of your Mazda whether you already have a CS SRI or if you want to get the whole package at the same time.


The CorkSport Advantage

2021 Mazda 3 cold air box

Design & Fitment:

The CorkSport Heat Shield for the SkyActiv 2.5T in both the Mazda 3 and CX-30 is designed to reduce the intake air temp and is achieved in a couple ways. First, by blocking out heat coming from the radiator, engine and transmission. Second, by providing fresh air to the air filter. We accomplish the first goal by creating a barrier between the engine and air filter as well as sealing the side facing towards the engine with a gasket to further reduce hot air from getting to the air filter. The cool fresh air is piped into the heat shield using the factory air box ducting and the open fender /wheel well. Installing the CS Heat Shield is quick and easy from the utilization of the OEM air box mounting points so that no modifications or other brackets are required.

Mazda 3 turbo heat shield test data


Testing of the CorkSport Heat Shield was critical to make sure the heat shield performed as designed. Testing included both spirited daily driving and remaining stationary to gain a good understanding of how intake air temps are affected with and without the heat shield installed. From these test we found that when the CS Heat Shield is installed, the average reduction in inlet air temperature was almost 10°F cooler over the duration of the test. Check out the graph to the right to see exactly how the CS Heat Shield performed against the CS SRI without the heat shield under similar conditions. The test was more demanding than a typical drive to show how both setups would perform under harsh conditions that you might see sitting in traffic on a hot day.

Materials & Manufacturing:

The CorkSport SRI Heat Shield is made from carbon steel that is laser cut and precision formed. The use of steel over other materials ensures good strength and provides a low amount of heat transfer through the material. The CS Heat Shield is separated into multiple pieces and is riveted together using stainless steel rivets to provide resistance to corrosion so they remain strong and continue to look good for a long time to come. All the heat shield sections are powder coated in wrinkle black to give a durable and great looking finish when installed in your engine bay.
