How the car should be
AV | February 17th, 2018
Installation wasn't too bad. 02 RSX from PA so there was lots of rust, but managed to complete in about 3-4 hours. Car sounds unbelievable. Nice and throaty when giving it some throttle, VTEC crossover is loud and sounds amazing Performance is definitely noticeable. Feels like a completely different car. Bought a hydroshield as well. If you've been debating on getting the CAI or short ram, get the CAI. You will not regret it.
Nothing but the best

That VTEC sound with injen will blow any other CAI off the street. This intake really opens up the car and gives the rsx that deep growl esp on the top end. Worth the price for sure and not a bad install. Just gotta be okay with cutting some wheel well plastic to have the intake fit right. And just install the top TWO bolts on the washer fluid reservoir because the bottom hole WILL NOT line up. Don't do what I did and drill a new hole to line it up because it will leak.... otherwise awesome intake.
The Best CAI for your type-s
Nick Paolantonio | May 25th, 2016
This CAI came in looking beautiful, unlike some intakes, it is placed down away from the engine bay so cool outside air is inducted rather than hot air from the engine. i was worried about hydro-locking my engine at first (my car is lowered) but after driving my car every day for over a year I've had no problems (i live in RI we get plenty of rain and snow). the induction noise is sick BTW! it really opened up the engine.
The Best

I previously had the Injen Megaram intake. Once I got headers, heat soak was horrible, even when I did wrap them. After switching to this, the butt dyno felt much more torque in the lower rpms, making daily driving a breeze. I would suggest getting they hydroshield, as well as taping up the holes in the fender liner when it rains (that's just me being picky, nobody sees it either)

Pretty easy install, but washer fluid container didn't quite align with the hole, so I had to do some minor modifications plus it leaked a bit one of the plug didnt fully seal. I don't use it anyway. I'm probably gonna delete it out. The car sounds great. When i start car it has a bit of a whistle sound. But driving just sounds so much better. And it does feel like it has more pull when I crank up the gas. I love it. Took me 4 hrs not gonna lie.
