Performance Enhancer. The AFE Silver Bullet Throttle Body Spacers (TBS) improve engine performance by creating turbulence in the incoming air just before it enters the combustion chamber. This results in a more complete fuel burn, increased horsepower, and enhanced throttle response, delivering a smoother and more efficient driving experience for automotive enthusiasts and professionals alike.
Construction and Appearance. Made from durable 6061-T6 billet aluminum, the throttle body spacer is precision machined for a lightweight yet strong build. It features a distinct serrated/helix design that enhances airflow and eliminates whistle noises common in other designs, finished in a clean, natural aluminum texture.
Installation. Installation is straightforward and uses all factory mounting points, ensuring a secure fit without the need for drilling or modifications. This allows for a hassle-free upgrade in most garage settings.
Warranty. This product comes with a limited warranty to protect against manufacturing defects.
Application. Designed specifically to fit the 2005 to 2009 Toyota 4Runner with a 4.0L V6 engine.
