Feed your engine more air! If you're making more than about 180 rwhp, this 64mm throttle body will get rid of a restriction in your intake. The more power you make, the more it will help. The stock throttle body is 56mm.
It also eliminates the possibility of lost screws and broken throttle shafts on hard-driven track cars. Call it engine insurance.
Direct bolt-in replacement for stock. Due to the larger diameter, it's a bit more difficult to drive at light throttle positions so it's not ideal for street cars that spend time stuck in traffic. Idle quality can also suffer. Available in both NA8 and NB style. Includes a new gasket and all hardware. Please note that we cannot ship this product to California as it will not meet emissions regulations.
