I purchased a MANN air filter for my M116 3.5 5yrs ago and have since put about 20k miles on the car.

Has anyone used an aftermarket "performance" style air filter on their cars? I'd like to stay away from K&N since I don't want to deal oiling the filter after washing it, etc. Any other good air filters out there? Just want to try something other than the MANN filter I have.
