It's not snake oil
This was the easiest bolt on I have ever dealt with,the throttle body adapter and cold air intake made a real snappy truck even better,you have to be careful when launching this missile now,just wants to break loose,love this set up thanks so much,I wouldn't hesitate to recommend these two products too anyone,mileage went up 2 mpg at the least
If you're going to buy this than buy the intake. Noticed a difference with just the throttle body spacer but had a bog to it. I ordered the intake and the two together are a drastic difference better low and definitely mid range response. Haven't noticed any in gas mileage. But do buy the set. I have full after market dual exhaust and k&n filter with factory air box.
