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

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

The aFe Power Silver Bullet throttle body spacer is engineered to improve off-idle torque and throttle response by optimizing the airflow into your Toyota's manifold. Precision machined from high-grade 6061-T6 billet aluminum, this spacer uses a patented serrated/helix design (US PAT 07055513) to create turbulence in the air charge. This turbulence breaks up the fuel/air mixture for a more complete combustion cycle, increasing horsepower and torque while improving fuel efficiency.

Unlike standard helix-only designs that often produce an annoying high-pitched whistle, the serrated entry of the Silver Bullet is specifically designed to eliminate intake noise while maintaining maximum airflow velocity. This kit provides a straightforward bolt-on installation using factory mounting points and includes all necessary hardware.
