aFe 46-33004 Silver Bullet Throttle Body Spacer Serrated/Helix Design Billet Aluminum - 6061-T6

The aFe Power 46-33004 Silver Bullet Throttle Body Spacer is a precision-engineered performance upgrade designed to increase horsepower, torque, and throttle response. CNC-machined from durable 6061-T6 billet aluminum, this spacer installs between the throttle body and intake manifold to optimize airflow entering the engine.

At the heart of the Silver Bullet's performance is its patented serrated/helix entry design, which creates targeted air turbulence in the combustion chamber just prior to intake. This turbulence breaks up the fuel charge for a more complete combustion cycle, translating to measurable gains in performance and improved fuel efficiency. Unlike helix-only designs common in competing products, aFe's hybrid approach also eliminates the annoying whistle noise — delivering a quieter, more refined driving experience.
