I have an oem filter on my 03 636. I pulled it last night and it was completely filthy. I was assuming I could pick one up for $10-$15...boy was I wrong. I called Performance, Sun Honda, and TFOG, all could get me OEM, BMC or K&N. As stated earlier, i didn't really want to spend in upward of $40 for an air filter.
I've heard that filters can be washed and re-used. So i'm all for doing that, but i have no clue as to how to do it w/o destroying my filter. Any help would be appreciated. I know BMC & K&N are 1 time buys, but i've also heard that sticking w/ OEM is best.
