aFe Silver Bullet Throttle Body Spacer (46-38005) boosts airflow and throttle response for 2007–2011 Tundra and 2008–2011 Sequoia V8 5.7L engines. Constructed from precision-machined T-6061 billet aluminum, this spacer uses a unique serrated/helix design to create air turbulence at the manifold. This improves the air/fuel mixture, enhances throttle response, and can increase both horsepower and fuel efficiency. Unlike helix-only designs, the serrated edge eliminates the high-pitched whistle often found in throttle body spacers.
