I have not even opened the air boxes yet to see if they are filthy, old or aftermarket already. But I am planning on replacing these soon and I have considered going to the oiled filter option which does seem quite popular here? I am coming from an E46 BMW M3, many discussions on this platform about changing the stock airbox/filter ended in forum battles over the value, etc. I don’t want to rehash those by any means. On that platform, unless you go to a full CSL airbox (incredible but $$$) the CAI’s are generally considered an HAI and to be avoided. So, many people just put a drop in panel filter in the already excellent design stock US airbox. BMC filters in this market had a great reputation, so…does anyone here use them or have any opinion on the value over K&N? They are available on eBay for $150 shipped for the pair, K&N can be had for under a hundred shipped with online specials from many vendors.
I welcome any thoughts, opinions, thanks!
