Upgrade to the BTB. The kit includes the replacement bracket, BTB Adapter, BTB, TPS Adapter Assembly, and all of the screws. Shown is the 99-05 TPS Adapter Assembly but we will supply the correct one for your model year, anything from 94 to 05.

Large throttle replaces the 55mm stock throttle body.  Effectively a 62% increase in cross sectional area allowing the the increased air flow needed for higher horsepower

We use a 70mm TB but we can supply a 75mm if you are headed further than 500WHP.
