    Specifications:

    Manufacturer's Part Number:
    46-31001

    AFE's Silver Bullet Throttle Body Spacers are constructed of durable 6061-TS aluminum billet and precision-machined for perfect fit. These throttle body spacers are designed with a serrated and helix bore to agitate the air flow just prior to entry into the engine block. This agitated air stream atomizes the fuel in the combustion chamber for a more complete burn cycle resulting in increased horsepower, torque and improved throttle response. Also, it minimizes the annoying whistle found in 'helix only' throttle body spacers.

    Features:

    • Durable 6061-TS aluminum billet
    • Precision-machined for perfect fit
    • Serrated and helix bore design
    • Increases horsepower, torque and improved throttle response
    • Hassle-free installation, includes hardware
