To soon to tell, only put 20 miles on it and no 0-60 runs yet, it's raining. Truck feels good but that could just be in my head. I also have a K&N drop in replacement filter I'm going to install after a while and see how it compares to the Fram filters I've been using.

I got mine from www.tsetruckstuff.com for about $100 shipped. You have to do a search for the part on the site. They didn't have it in their warehouse but they had it sent from Airaid themself and it got to me in 3 days. Haven't installed it yet but I'm interested on hearing how much difference in fuel economy everyone is getting.
