I had previously had some difficulty finding a good CAI that would actually fit my car (I have a 2007 Acura TL S-Type/3.5, not 3.2 Litre), and for whatever reason that particular year & model engine does not come equipped with a M.A. Sensor on the intake, which precluded me from getting a K&N Typhoon, or any other Ram Air intakes that would work on my car. Well, I lucked out when I found the Injen CAI for my car. It came to me real quick, was tough to install, but works GREAT! Love it!!!
Easy to put on--approx 30 min overall. 1st time ever doing this on any of my cars. Didn't have to mod anything like others that I've read. Throttle response appears to have increased. Nothing dramatic though, but am pleased with product and $$$ paid overall compared to the other more expensive brands.
