Description
Engineered to improve combustion efficiency and throttle response on GM 5.3L V8 platforms, this aFe Silver Bullet throttle body spacer uses precision-machined 6061-T6 billet aluminum and a serrated/helix airflow profile to introduce controlled turbulence just before the intake charge enters the engine. That optimized air/fuel mixing can yield measurable performance gains—tested increases up to +10 horsepower and up to +14 lbs. x ft. of torque—while remaining a compact, bolt-on enhancement for Silverado, Sierra, Tahoe, Suburban, and Yukon V8 applications.
