My air filter after the last big dust storm is full of dirt/dust. I need to buy a new filter. What is the part number for a replacement & surely they have to make a better looking filter then that fuzzy gray thing we have. Done side to K&N & I may go with a K&N for the better looks plus better flow. Back to K&N downside is that they come over-oiled & it gets oil on the MAF sensors. This can lead to false reading if not cleaned with a good contact cleaner spray. There has to be more choices?? I was reading the K&N has to be trimmed to fit also. Any suggestions?
