I disgree i had to call them 4times during the install. They helped me every time i stated sorry i have so many questions they said thats what where here for. There are a lot of aftermarket parts we have to make adjustments for a little rubber on the line really works. I also went from 24.2 mpg to 27.3 with cc at 70mph for 30 miles the same i do dailyot the way to work. One more note I heard the exhaust tone changed with the intake so i left a v.m. for J.R. and he called me back at work to discuss the issue with me buy the way it did not change except for the roar the intake makes. Hats off to J.R. for a great intake where can you get 20ish h.p. for 300 bucks.
