Silver Bullet Throttle Body Spacer for 2011 - 2020 Ford F-150 by aFe Power 

Silver Bullet throttle body spacers create turbulence in the air flow at the point just prior to entry of the engine - increasing performance, as well as improving throttle response and fuel efficiency. 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.


  • Constructed from Durable 6061-T6 Billet Aluminum
  • Unique Serrated/Helix Entry Design Creates Turbulence and Eliminates Whistle Sound
  • Increases Air Intake Speed, Improving Performance & Throttle Response
  • Adding a Silver Bullet Throttle Body spacer lengthens the intake track which helps increasing intake air speed increasing performance and improved throttle response.


  • 2015 - 2020 Ford F-150 V8-5.0L
