I went to autozone the other day and got an intake pipe, an air filter and and an arm. I saw how turbokits did their CAI so I basically paterned this one after it. installing it almost exaclty the same way. and it works well, it sounds really nice. I'm sure it doesn't add as much HP and torque as the turbokits one, but In total I paid approximately $70 for it. The only thing I worry about is getting water sucked through the intake. I've had it in for a month now and haven't had any problems.
