Review on AFe Power Silver 46 38006 Throttle by Gustavo Mathew

Absolute snake oil. Easy to assemble and looks very high quality. The first impression was not very good. The whistling sound it makes is almost deafening and constant at a cruising speed of 65 miles per hour. Drove it a few hundred miles and took it to friends on a dyno to really see it. (Prior to installation, I ran the truck on a dyno.) The truck performs better without the spacer and sounds a lot healthier. I would not recommend this product for any reason. You can't even see it when it's installed, so it's really just wasting money and making an awful noise while driving.
