AFE: Silver Bullet Throttle Body Spacer Ford F-150 97-03 V8-4.6L/04-10 V8-4.6L (2-Valve)/ 97-03 V8-5.4L

Serrated/Helix Design:
The Serrated/Helix combination design creates intake turbulence in the combustion chamber. This turbulence breaks up the fuel which creates a more complete combustion cycle increasing horsepower, torque and improving throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with Helix only designs.

6061-T6 Billet Aluminum Construction:
All Silver Bullet Throttle Body Spacers are constructed from 6061-T6 billet aluminum precision machined for light weight, high strength and perfect fit and finish.

Longer Intake Track:
Adding a Silver Bullet Throttle Body spacer lengthens the intake track which helps increasing intake air speed increasing performance and improved throttle response.
