I've heard so many things about the Injen Cold Air Intake (cai) being the best on the market I am finally happy I have one of my own. I am an RSX-S owner and every single owner of that car swears by the Injen CAI so I went along with the crowd for once and I'm glad I did. This thing gave my car a little extra power but nothing noticeable, what is very noticable is the new awesome aggressive sound I get from the engine whenever I'm over 5k rpms, it sounds like a monster. I love the discreet hissing sound it makes when I start up the car too, kinda wish it was more noticable inside the car, I had to open the windows to hear it, it's just a cool sound. Install was easy if you know what your doing it shouldn't take too long, its a pain getting most stock airboxes out, and some light modifying needed to be done to get mine fitting properly but nothing difficult just had to cut a little part of the wheel well to fit the intake through. The hydroshield is a MUST! It will give you piece of mind and luckily my CAI came with a free hydroshield and this intake package was the cheapest one I found online with free shipping as well. Great service and great company

Very easy to install. Looks great and sounds even better. It's amazing how better this intake kit makes it sound. It also improves the throttle responsiveness.
