aFe Power 'Silver Bullet' Throttle Body Spacer Silver 2013-2021 BRZ / 2013-2016 FRS / 2017-2021 GT86

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.

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. Adding a Silver Bullet Throttle Body spacer lengthens the intake tract which helps increasing intake air speed increasing performance and improved throttle response.

This Silver Bullet throttle body spacer uses all factory mounting locations providing stability and a hassle-free installation.
