fredbmw 12 Report post Posted November 30, 2020 Hi I’m looking at taking the nasty looking POD filter out of my M3. I’ve heard the 325 or maybe 328 filter housing is the same as M3 - all info I come across is from US based websites which I don’t trust for M3 discussions Anyone know for sure?

Any idea where I can pick up a M3 air box? Quote Share this post Link to post Share on other sites
nath 134 Report post Posted December 1, 2020 Alpina seems to have a different box again- unsure on diameters though Quote Share this post Link to post Share on other sites
