Silver Bullet Throttle Body Spacer 46-32007 for 5.7 / 6.1 / 6.4

The Silver Bullet throttle spacer generates up to 12 HP additional power and a torque increase of up to 20NM.

It is machined from precision-machined 6061-T6 block aluminum and features a serrated/coiled 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, providing more power, torque and improved throttle response.
This spacer works with the original and aFe POWER air filter systems.

Serrated/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 intake whistling that occurs with other pure helix designs.

6061-T6 aluminum construction

All Silver Bullet Throttle Spacers are precision machined from 6061-T6 billet aluminum to ensure low weight, high strength and perfect fit and finish.

Longer intake tract

Adding a Silver Bullet Throttle Spacer lengthens the intake tract, increasing intake air velocity, increasing power and improving throttle response.

Can be combined with aFe POWER air inlet systems

This throttle body spacer fits aFe POWER air intake systems: 51-12172, 54-12172, 51-12162 and 54-12162, but requires intake pipe modification.
It does NOT fit the aFe Power air intake systems: 51-72203, 54-72203, 51-72203-R, 54-72202, 51-72202, 58-10003D, 58-10003R, 54-12162-C, 51-12162- C, 54-12172-C, 51-12172-C.

Only suitable for original throttle bodies.
