aFe Power Silver Bullet Throttle Body Spacer for Select Chevrolet/GMC 2014-2026 (V8-5.3L)

Fits select 2014-2026 Chevrolet Silverado 1500, Suburban, Tahoe, and GMC Sierra 1500, Yukon, and Yukon XL (V8-5.3L).

The aFe Power Silver Bullet throttle body spacer is engineered to optimize your engine's combustion cycle by improving the air-fuel mixture. Precision CNC-machined from 6061-T6 billet aluminum, this spacer features a unique serrated/helix design. This internal geometry creates air turbulence just before the intake manifold, allowing for a more thorough air/fuel charge burn. The result is a measurable increase in horsepower, torque, and throttle response across the RPM range.

Beyond performance gains, the serrated design specifically targets and eliminates the high-pitched intake whistle often associated with smooth-bore spacers. This kit is a direct-bolt-on upgrade that uses factory mounting points for a straightforward installation.
