About this product

Part #: 46-31001

Silver Bullet throttle body spacers create turbulence in the air flow at the point just prior entry into the engine increasing horsepower, torque and improving throttle response and fuel efficiency. Silver Bullet throttle body spacers are constructed out of durable T-6061 billet aluminum and using a unique serrated/helix entry to create turbulence at the manifold while eliminating the annoying whistle found in other helix only throttle spacers.

What made you choose this particular product?
Figured it'd be an easy drop in part to replace the OEM air filter.
Was it easy to install? Any installation tips that will help others?
Yep. Just dropped it in the air box.
Once you've had a chance to use the product, did it meet your expectations?
Seems to go well the TRD Intake Flow Accelerator. Saw a minor increase in MPG and haven't had any heat issues or problems yet.
Any additional comments?
Will see how the Orange Virus tuner helps with the addition of this high flow filter and the intake accelerator.

What made you choose this particular product?
Performance as well the clean look with the aluminum cover.
Is this your first time buying from this brand? Did you consider other brands?
Yes, I was thinking of Dinan but aFe was just more my style.
Was it easy to install? Any installation tips that will help others?
It was quite easy, just make sure your stock intake boot is angled correctly or it won’t fit correctly until you adjust that first.
Once you've had a chance to use the product, did it meet your expectations?
It was more than I could of expected, the sound the feel, I enjoy every moment.
