Description
Silver Bullet throttle body spacer is constructed from precision machined T-6061 billet aluminum and is designed using a serrated/helix design that creates turbulence in air flow at the point just prior entry into the engine. This turbulence helps the air/fuel charge burn completely providing increased horsepower, torque and improved throttle response.
This throttle body spacer is 50-state legal (CARB E.O Number D-516-2).

aFe Power Silver Bullet Throttle Body Spacer Reviews

The engine runs a bit smoother in mid-range, probably due to better mixing of the PCV and EGR gas with the air through the throttle body. There's no measurable manifold pressure loss compared to without it, so there can't be any power loss. Can't see any reason for any MPG loss either. If there's any gains, it's probably in the mid-range due to the previously mentioned mixing of intake air, PCV and EGR gasses. I used silicone gasket maker instead of the gasket and peeled off the excess after curing. This eliminates any possible gap from the gasket in the air stream, and the spacer itself makes no noise (stock intake).
