Took a couple min, bout 15-25. Wasn't really hard, just needed somethin to get a few of the bolts off. I'm not sure, but I think I'm getting a slight mpg increase, but the throttle response has an amazing notice, I can spin my tires all day with it; helps out especially with the a/c drag.The CAI sounds mean too lol
I am, think I'm noticing a slight variance now when I punch the throttle, acts like a V8 if you punch the gas alot and drops the mpg just a tad, versus before when I could all day long and not do a thing. will.update on any better mpg gain through normal/baby driving.
