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.

Install was pretty easy but the pictures were pretty blurry on instructions I went on website same pictures but at least I could zoom in on them

Was extremely easy to install, although the instructions could have been more specific in some areas. So far it appears to boost mileage and performance as described.

I liked the performance of the spacer however the brackets for the throttle cable did not fit my truck, and the directions were basically useless

Pictures on instructions could be better and wording a little clearer. Installed with no modifications. Will have to see results are.

Fitted perfect on my 2006 Dakota SLT 4.7 eng. Gain power, accelerates easier, also have been saving noticeable on fuel! You gain power so in order to take off you just touch the gas and is going! That alone saves fuel! installation was as easy as that! No complains!!!! Love it!!!!

very easy to install. i don't look for gas miles to change, i know my truck and light stop and go driving is where i feel more power. AND IF YOU READ THE OTHER REVIEWS. YOU NEED TO BUY LONGER COUNTER SINK BOLTS TO ATTACH THE INTAKE RISINATOR BRACKETS.ACE HARDWARE HAS THE BOLTS IN THE STORE. 20 OR 25 MM LONG WORKED FOR ME

I just installed this unit on my 2001 Dodge Dakota 4X4 with a 4.7L engine, automatic. It was getting 19.2 MPG before the installation and now is at 20.4 MPG. The power difference is noticeable right off idle to about 3000 rpm. I am pleased with the unit generally. But I gave it a 4 star rating due to the incredibly bad instruction sheet that comes in the box. Also I was shorted the three longer throttle body mounting bolts that are listed in the parts breakdown. I went down to the local hardware store and bought them. Also be aware that if you have my rig, you will need to cut one of the air silencer body mounting legs off to use this spacer. Or you can buy an aftermarket cold air package and remove the stock stuff.

I've had this on my 04 Dakota for about 4 tanks of gas. I do feel a slight increase in power, but nothing overwhelming. It has a slight whistle, but I like it. However I was hoping for some mpgs and I got nothing. If you want a small amount of performance, get it.
