Silver Bullet throttle body spacer for Tahoe, Sierra and Yukon

The Silver Bullet throttle body spacer is made from precision machined 6061-T6 billet aluminum and features a serrated / helical design that creates turbulence in the airflow at the point just before it enters the engine, optimizing the combustion cycle.

This turbulence contributes to the complete combustion of the air/fuel mixture and ensures more power, torque and improved throttle response.
This spacer works with the original and aFe POWER air filter systems.

Toothed/helix construction

The toothed/spiral combination design creates intake turbulence in the combustion chamber. This turbulence breaks up the fuel, creating a more complete combustion cycle that increases power and torque and improves throttle response.
The toothed/helix combination design also reduces the intake whistling that occurs with other helix-only designs.

6061-T6 aluminum construction

All Silver Bullet throttle body spacers are precision machined from 6061-T6 billet aluminum to ensure light weight, high strength and perfect fit and finish.

Longer intake tract

Adding a Silver Bullet throttle body spacer lengthens the intake tract, increasing intake air velocity, boosting power and improving throttle response.

Fits:

Only suitable for original throttle valves!
