Performance Overview

This Silver Bullet throttle body spacer produced 10hp and 14lbs. x ft. of torque by creating turbulence in the air flow at the point just prior entry into the engine. Silver Bullet throttle body spacers are constructed out of durable T-6061 billet aluminum and using a unique serrated/helix entry to create turbulence at the manifold while eliminating the annoying whistle found in other helix only throttle spacers. This is a great bang for the buck add-on product
