I finally got around to changing my filters today. 120000 miles and they really showed it, completely clogged. I also had to clean out the air box, reminded me of cleaning my gutters at home. I can already tell a difference in the volume of air comming out of the vents, and the smell or lack there of. I will never go more than 30K before changing again.
Thanks to jschmid :bigok: for posting that diy.
