AEM 21-841DS Cold Air Intake System, Black

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!

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

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!!

Pain in the butt to put on but if it fits right from the start it performs well

Honestly this was pretty bad nothing line up correctly huge gap between mass air flow sensor and airbox pictures shown

Had to “modify” it a little because it was rubbing again my headlight but was well worth the money

Your browser does not support HTML5 video.  Definitely a good-looking intake and did make a difference on the butt dyno, but that might be because my old filter had over 15k miles on it 😅 regardless, looks real nice in the engine bay and im happy with it, especially at just over 200 bucks. AFE wanted over 400 for theirs and this one's arguably just as good. Worth the money, no question. Oh, and heads up, intake noise with this is minimal

My feel major horsepower boost in my 323i and it gas nice sounds when accelerating. Its a must buy!!!!
