Mishimoto recommends that this intercooler kit, with or without the optional air intake, is not used with the stock ECU programming. It is highly recommended that the customer is able to retune the vehicle’s ECU after installing the intercooler kit. Power gains will vary depending on the size of the turbo, exhaust system, fuel system, and type of ECU tune that is applied to the vehicle.

This kit is rated for approximately 600 whp, or 30 psi of turbo boost. Exceeding these horsepower or pressure limits may require a custom-sized front-mount intercooler.
