The stock intercooler leaves a lot to be desired in terms of cooling performance and efficiency. Our upgraded intercoolers are the solution for cooler EGTs, improved efficiency, and durability that far outclasses the stock intercooler. An upgraded intercooler is an excellent solution to support powerful upgrades such as high flow injectors and turbos.
