AEM28-20231 DryFlow Air Filter

One of the few mods I actually felt right away in my 1999 323i. No doubt about how this product improves acceleration and throttle response compared to the brand new MAN OEM filter I had in.

Very nice work. My car runs better with it. My old one was bad.

I always use AEM filters, just drop in and go. No need to oil up, just clean once a year or every 15k.

Perfect size for my e46 330ci. Seals to air cleaner box like OEM

Awesome!
