This is the Grimmspeed top mount intercooler that has been designed to provide maximum cooling efficiency with minimal restriction. Grimmspeed understands that because the top mount intercooler design is more prone to heat soak, they developed a solution that delivers performance while reducing intercooler temperatures to help prevent pre-detonation or knock which allows for more power and performance.
Grimmspeed designed this intercooler with two unique end tanks. The first end tank accepts the hot air charge from the turbocharger and feeds the air into the intercooler core. The second end tank receives the cooled charged air from the core and delivers it into the throttle body. These end tanks are precision cast and machined, and the intercooler core will have a bypass valve flange that is milled flat and will come with stainless steel studs that are permanently installed to ensure that the aluminum threads don't become damaged. These end tanks are welded to a high-density bar and plate intercoolers before the entire assembly is pressure tested, cleaned and sealed just before shipment.
**The intercooler core will come in a black powder-coated finish for those of you who want the cleaner, streamlined stealth look in your engine bay.**
