• Manufacturing Quality and Warranty - Amazing part quality and manufacturing techniques, with outstanding warranties on the entire system.

Intake and Charge Air

One of the first mods to the car is opening up the intake tract before the turbocharger. The OEM air filter and air box assembly becomes a large restriction once you reach ~40hp over OEM output. With additional boost level over OEM, we work to keep the charge air coming out of the turbocharger as cool as possible by upgrading the Intercooler to the ETS Front Mount. Cool Air = Horsepower!

• Important Note: Air Box - You will see it includes a comprehensive air box design that keep the radiant heat off of the intake filter as well as the heat coming directly from the radiator fans that can commonly cause a "bouncy" idle.
