46-38015 | aFe Power Silver Bullet Throttle Body Spacer (2011-2022 Corolla L4-1.8L)

• 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.
• 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

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.
