Bought this for a 2008 Infiniti M35x and have been happy with it so far. The factory air system was too restrictive and this CAI really opened it up. For the install, the drive side wheel well had to come off and supposed to stay off but I didn't like that. I ended up modifying the wheel well cover by cutting a hole in the bottom of it and added "vent" holes as well so I could put the cover back on the car and still get the necessary air flow. Overall seems to be a great quality and I love it.

great product

The customer service was great. Received my product real quick. Easy to install with the instructions that were provided. Looks great after install. Definitely buying more from this site.

This is a nice intake!

Much better than most intakes out there. I feel a noticeable difference especially when I get on the accelerator! During normal driving, my gas mileage went up about 2.5 mpg (I also installed new plugs).

Great product!

This air intake was really easy to install on my 2006 Infiniti M35. Its a cold air and a short ram and I went the easy route with the short ram and couldnt be happier. Performance is great, im getting better throttle response and more power. The polished version looks very nice and the sound is amazing when you mash the pedal, yet is quiet during my everyday drive to work. Overall I am highly pleased with Injen and would buy intakes from them in the future.
