aFe Silver Bullet Throttle Body Spacer for 2003-2024 Toyota 4Runner & FJ Cruiser (V6-4.0L) 46-38008

Fits 2003-2024 Toyota 4Runner and 2010-2014 Toyota FJ Cruiser (V6-4.0L).

The aFe Power Silver Bullet throttle body spacer (MPN: 46-38008) is precision-machined from T-6061 billet aluminum to optimize the airflow into your engine's manifold. It features a unique serrated/helix entry design that creates air turbulence just before entering the combustion chamber. This turbulence improves the air/fuel atomization, resulting in increased horsepower, torque, and sharper throttle response.

While many helix-style spacers produce an annoying high-pitched whistle, the aFe Silver Bullet is engineered with a specialized serrated combination to eliminate noise while maximizing air volume. This spacer is compatible with both the factory intake system and aFe Power performance intakes for a straightforward bolt-on installation.
