took me 4 hours to install mine and this was the first time doing a cold air intake. Its badass and hooked up very efficient. I do wish the instructions were a little more specific on what they are talking about in each step as some of the steps were vague. Overall its installed and seems to work very well.

Not bad...

I'm new to aftermarket modification, so the rating for Ease of Installation isn't really fair. 27 mpg was boosted to 30 mpg driving conservatively. Engine sounds stronger with full throttle acceleration, and it gets off the line a little faster, too. Not a bad investment overall.

Cheesy, wouldn't install correctly on throttle body and grommet that went on vacuum hose was too small and left big enough hole too allow uncontrolled air to enter. I would not recommend buying this, the whole system was very cheesy.
