About this part

This Process West top mount intercooler and intake combo (PWCAI07 + PWTMIC06B) fits the 2015–2020 VA-chassis STI. The top mount core is 530mm x 193mm x 90mm and rated to 400WHP, and the intake side adds a laser-cut, CNC-folded heat shield and a K&N high-flow filter, finished in powder coated wrinkle black. Process West develops its cooling from a 3D scan of the actual engine bay rather than a generic core, and the kit includes the TMIC, a Y-pipe/throttle body and BOV return silicone kit, an intercooler splitter and a hardware kit.
