I was servicing my girlfriends Subaru, I had bought a NAPA Gold air filter because they are always good quality and I never have had any problems with them. I messed with that filter for a good hour and finally tore it trying to get it in. Went and bought a Fram and it fit perfectly, popped right in in 1 minute and sealed perfectly. I didn't post this to knock NAPA or Wix, they've always been great, but Fram made me very hapy today.
