aFe Silver Bullet Throttle Body Spacer for Select 2003-2015 Toyota (V6-4.0L) 46-38002

Fits select 2003-2015 Toyota 4Runner, FJ Cruiser, Tacoma, and Tundra models equipped with the V6-4.0L engine. This high-performance spacer is designed to optimize airflow and combustion efficiency by inducing turbulence at the intake manifold.

The aFe Silver Bullet throttle body spacer is precision-machined from durable T-6061 billet aluminum. It features a unique serrated/helix design that creates air turbulence just before entering the combustion chamber, leading to improved throttle response and increased torque. Unlike standard helix-only spacers, this serrated entry is engineered to eliminate the high-pitched whistling sound often associated with throttle body modifications. This spacer is compatible with both factory and aFe Power intake systems.
