This album contains photos of the custom throttle body porting and polishing services I provide for any engine. This modification is an easy, cost effective, and bolt-on one yet has a substantial effect on how the engine and vehicle runs, namely in terms of crisp throttle response, quicker and much stronger boost response on turbocharged vehicles, and a wider torque and powerband. My rates vary normally from $150 to $250 depending upon the throttle body.
