I'll probably be the only person to actually say my MAC parts are worth what I paid for them. If you get anything chromed, you have to do some polishing from time to time. I've had this particular CAI for over two and a half years and it still shines like new money when I get done rubbing it a little. My exhaust has been on for 9 months or so and the coating is still intact and have had no problems ever getting it to seal up and fit properly. I'm not saying MAC is the greatest in the world, but I see so many MAC haters in various places that someone has to play the other side. I'm a satisfied MAC customer so I reckon I can handle that task.
