I've been reading up on 500i air filters, and am wondering what y'all are running...There's a blown up 500i on it's way to me, and it's missing the filter shroud, as well as a damaged air filter. Assuming it's worth a rebuild, I'll be needing a new filter setup.
Here are a few notes/products I've noticed:
· Rubber gasket under the foam center washer, to seal the OEM filter tighter
· Outterwears Pre-filter atop OEM
· Pool noodle slice, on the inside of the filter cover, to press filter tighter
· Oiled Foam units like 'westcoast saw', egan, and max-flow
Since I'll be needing a new filter and shroud regardless, the foam kits would all work out to ~$100. An OEM Shroud + Filter is around $70, so adding an outterwears + gasket will also work out to a similar price too.
The Egan and Max-flo's look like they have the most surface area
