The GR Corolla has become one of the most popular hot hatches on the market, especial among track enthusiasts. Its 1.6L three-cylinder turbo motor shared with the GR Yaris is an engineering marvel and offers plenty of room for growth. Pairing that with the all-wheel-drive system, great suspension, and stiff chassis, you have a near perfect track machine.

The stepped core design increases the overall volume of the intercooler core by 45% and the surface area by 73%. The step core allows for maximum surface area and volume but utilizing all the available space without requiring the bumper or any core supports to be modified or cut. The tanks were carefully engineered to optimize flow through the lower and upper cores resulting in incredible smooth and even flow with maximum heat transfer.

Each Intercooler kit includes motorsport grade hoses and clamps designed specifically to hold up to high boost. High grade 5-ply silicone construction makes the hoses incredibly strong and have a matte black finish for a more stealthy performance look. The clamps are a unique new design that incorporates a bead lock system to help hold up to extremely high boost.

The performance of the OE Tube & Fin Intercooler is actually quite impressive. It is able to drop charge air temps by almost 150°F which is quite good for even some aftermarket performance intercoolers. The main drawback of the factory unit is how quickly it heat soaks. Post cooler charge air temps can quickly climb by 60°F. The limited surface area really hampers the overall cooling capacity here.

The TIG-Welded Cast Aluminum end tanks increase the overall strength of the intercooler. This improves durability and longevity so you can be confident it will hold up to hard driving conditions. The CSF x Jackson Racing Intercooler mounts in the factory location and requires no modifications to the bumper or crash bar. The OEM ducting does requiring trimming to be used. This ducting helps guide air into the upper stepped core.
