: Easy…first purchase the K&N filter cleaner and oiling kit.. Then loosen the two retainer belts holding the arm in place. Remove arm. Unscrew the screws holding the plate that holds the cone coupling. Remove plate. Remove cone. Apply cleaner to remove old oil and dirt. Hose off cleaner. Let dry. Apply new oil. Let dry. Reinstall. (a lot more fun then getting under the m and doing a half ass job). Here is a cool tip for the dinan. Drill a 1 to 2 inch hole in the top of your left brake-cooling duct this will get more cold air and get positive pressure to the filter chamber where the con resides. I have had mine this way for a year on my 99 M3 with do problems. Makes sense to me. Korman also uses this idea on their e36 m3 “ram air Intake” ( they assure you that you will not lose noticeable brake cooling).
Guess what. Apparently, when the Dealer installed the Intake as part of my Supercharger installation, they already knew of this trick....I reached up into the brake duct to see if I could feel the K&N and sure enough, there it was.....It was a whole big enough for me to put my fist through.
On a slightly different angle, have you noticed the quarter inch gap above the front bumper and under the half inch vertical plate which goes under the headlamp, through which, with a flashlight, you can see the K&N? I was concerned that the rain, when driving through a rain storm would have too easy an access to the filter. So would the dirt...So, I bought a coil of some half inch black weather stripping, cut off about a foot, and inserted it into that gap....Seems like a good way to protect it a bit from the elements..
