Serrated/Helix Design:
The Serrated/Helix combination design of the Silver Bullet Throttle Body Spacer for the Lexus IS350 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.

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

Emissions DisclaimerThis product is not currently CARB exempt and is not available for purchase in California or for use on any vehicle registered with the California Department of Motor Vehicles.
Fitment Note

This item will work with all aFe POWER intakes systems.

Silver Bullet throttle body spacers create turbulence in the air flow at the point just before entry to the engine – increasing performance, as well as improving throttle response.
