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.

Was reluctant to purchase the Silver Bullet for my new 6.2 Rapture engine but very glad I did. I installed my new engine without it first and then added it. The difference in power is very noticeable.

This was a very easy upgrade it for my 6.2 L Ford super duty. It does make a pleasant whistling sound at 2000 RPMs and it is difficult to say if there is an improvement in performance but collectively with other enhancements it theoretically has to make a difference.The manufacturer claims up to 10 HP and 14 lb/ft torque.I have also done the aFe cold air intake with my 2015 F250... definitely a big improvement and the sound under the hood is exhilarating when I step on it!Great product for sure. Made in USA too!

I can't really tell any HP or MPG increase but hopefully it can't hurt to have it installed. FYI...it does whistle. I didn't expect it to. But it's not a bad thing. It almost sounds like a little turbo!

No noticeable improvements!!!! Very dissatisfied with product. Definitely did not meet expectations installed on a 6.2l ford

I installed this on my new 2013 F150 FX4 6.2L as on AFE website and speaking with them it does fit unlike the part finder on Amazon's website. I installed the aFe 54-11902-1 Magnum Force Stage-2 Cold Air Intake System with Black Tube as well and what a huge difference with both installed. Averaging 17 mpg with 33x12.50x20 tires stock was lucky to get 15 with stock tires.

No noticeable difference in anything but noise. The theory behind this makes sense, for a $100, figured I’d just see. Whistles which is a little annoying but manageable. Makes no noticeable difference other than that.

Top quality. Easy to install and can be done without a qualified technician. I now have the only Raptor in my country with this upgrade. Thanks a lot.

In the 6.2L ford Intake there is built in air straighteners making this product not able to do what it was designed for. The product itself fit and finish was good
