Engine air filter. I don't usually bother with the cabin air filter. For years, I had cars that didn't have those. I see very little value in them. As long as the air flows okay through the vents/AC, I'm happy. But I will change engine air filter at recommended intervals.jzchen wrote: ↑Wed Oct 14, 2020 5:32 pmCabin filter or engine air filter?darthpuppy wrote: ↑Sat Sep 07, 2019 5:12 am BTW- The air filter change was easy to do.
