Changed the air filters on the new to me 05 coupe, as I did not see them specifically listed in service records, car has 75k on the clock, they weren't original unless the factory tech had greasy fingers, but didn't do well on a light test. Lots of bug carcuss and moth wings in there, and cottonwood fluff. Come spring I may treat underside of black plastic housing to reflect/insulate heat cause engines love cold dense air.
