I bought this intake for my 2007 Mazda RX-8, and I expected it to be a fairly easy job. It wasnt too hard, as I am a technician, but be prepared to take the wheels, splash shields, bumper, and bumper support. Also, the clips might be crusty, so inspect and buy new ones beforehand. Aside from that, the intake fit perfectly. I would like to say I feel a slight power gain, but it's not much. From the videos, you can hear it pretty well, but I'm straight piped, so you can't hear the intake over the exhaust. Overall, I would recommend this intake to any RX-8 driver who wants a little more out of their car. It looks great and works well. 5 stars from me.
I gave this intake a 4 out of 5 because I love the performance of the intake, nothing better on the market for an rx8, I can definitely feel the power increase and even made my accelerations feel like the motor is running smoother compared to other aftermarket intakes I've tried. This intake DOES come with their dry filter sock, I bought one as an add on to find that the intake included one, so now I have 2. My only complaint is the amount of individual pieces there are A LOT of hose clamps used on this intake which gives a lot more opertunities for an air leak, I think it could have been engineered to have less pieces and there for less chances for air leaks. I STRONGLY recommend buying this intake
