Installed this on my 2012 RAM 1500 truck a couple weeks ago and so far so good. Both cold and warm idle is noticeably smoother. Throttle responsiveness has increased. I switched to the colder NGK model 6619 iridium spark plugs as recommended by Edelbrock. My fuel consumption has improved by about 4.5 highway/2 city. Most importantly though, it really goes when I step on the gas now. :-) The price is certainly high and didn't qualify for my AutoAnything 15% off coupon, but overall I'm satisfied.
