I guess you could, but then your SO will scream some obscenities at you.
Warm water, some dish-soap and rinse under running water inside to outside. Then reapply K&N Filter oil with a spray can, let dry and replace.
But if you really like your bike go buy a BMW brand paper-cloth filter and get a new one every 12,000 miles or so.
The K&N are great filters but IMHO they let too much large paticles through until they get dirty and the dirtier the better they work - to a point...

Do yourself a favor and throw it in the trash. Never mind all the manufacturer "data" and hype.
I had one on each of my Diesel on road trucks. They get oil analysis periodically to check oil condition. On the OEM paper filter I would see 4-5 PPM of silicon (dirt). Once we went to the K&N's the silicon jumped to 35+PPM. The microscopic slides showed dirt grains and same size metal shavings suspended in the oil. Other wear metals were higher than normal as well. My mechanic ran an AFE (high $ K&N) and I sent a sample in for him. Guess what? High silicon levels too.
Once the K&N's went in the trash can the silicon levels returned to 5PPM. The K&N's were properly lubed and one was new.
I wouldn't give a nickle for all the K&N's in the world. But what do I know, I don't go by K&N's claims, I only go by lab analysis.
Good luck.
Hold a K&N up to the light and see all the "holes". But according to K&N the "holes" are a good thing.
Now will start all the people who have "never had a problem" running K&N's. Of course not, wear is cumulative

Air Filter Numbers
OK I am convinced now that I do not want the K&N filter that is on the bike right now.
Is there a list of filter numbers by the various filter manufacturers that shows the BMW equivalent.
Cheers.....John
