The aFe Silver Bullet Throttle Body Spacer is an easy and economical way to increase performance and gain fuel economy. The Silver Bullet is positioned between your engine's throttle body and intake manifold. This additional space increases the volume between the throttle and cylinder, improving volumetric efficiency. The serrated/helix design inside the spacer creates turbulence to more thoroughly mix the air/fuel charge, improving combustion. The result is more horsepower and torque, and improved throttle response.

The Silver Bullet is machined from T-6061 billet aluminum for long lasting performance and durability. And the serrations at the spacer entrance reduce the annoying whistling at idle and cruising speed that is characteristic of other throttle body spacers.

Everything to complete the installation is included with the Silver Bullet, including comprehensive instructions. The Silver Bullet is backed by a limited 2-year warranty and it's made in the USA.

So after ordering stuff from CARiD I went to the local parts store in my area just to see if I was get a good deal as I asked the parts person if they heard of CARiD and he replied yes there a scam, so I became very worried and the part I ordered from CARiD was way cheaper so I put the worries in the back of my head and waited for the part to come from CARiD then the part arrived and the worries when away, I installed the part and was very happy with the product I ordered, so far I’ve ordered a lot from CARiD and will continue ordering.

Great Product
This thing went on fast and although it may not generate crazy power gains, I like the whistle. It will whistle... reminds me of a turbo and it seems to go well with my MagnaF exhaust. I also notice my cars mpg has increased, but I have coupled this item with other after market parts as well. Worth it, I like the name too. My car is silver, and a bullet.
