This Air Intake System is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

  • Mixed feelings.
Let me start by saying this will not fit BMW 328i (E90/91) with the factory upraded headlights (HID/non-halogen). The ballist mounted on the headlight interferes with proper fitment. I had to "modify a hole in the front of the intake box to allow fitment. This does increase engine noise and throttle feels slightly more responsive. Quality of plastic does not feel like the best but it's half the price of the afe intake kit. Far price from a company with a good reputation ... show more

  • Good product for its value
Had to “modify” it a little because it was rubbing again my headlight but was well worth the money

  • Best aftermarket intake around
The see through window into the intake is an awesome added touch, and hands down this is the best product on the market for adding performance!

  • Cheap don’t waste the money. Go with the AFe air intake
Made poor let cheap. Big gap where filter mounts to air box. Spend the extra money and go with AFe much more power and way better quality. You will not be disappointed!!

  • The Fitment is not good
Pain in the butt to put on but if it fits right from the start it performs well

  • Incorrect Fitment
Tried to install, fitment is incorrect and has gaps from the head where the filter enters to the box its self. Air is coming out and def not worth the price I spent will most likely uninstall and return/ replace it with another one.
