How does a throttle body spacer improve performance?

The serrated/helix design creates turbulence in the air entering the engine. This turbulence helps the air mix better with fuel, leading to more efficient combustion and potentially increased horsepower, torque, and improved throttle response.

What material is the aFe Silver Bullet throttle body spacer made from?

It is constructed from durable T-6061 billet aluminum. This material is chosen for its strength and resistance to corrosion, ensuring a long service life.

Does this throttle body spacer make noise?

No, this spacer uses a unique serrated/helix entry design specifically to create turbulence without the annoying whistling sound often found in other helix-only throttle spacers.
