you're not alone.. on my old civic, the fram air filter was definitely letting in more dirt. Usually you could see the dirt accumulate on the filter's outside facing side. But over a year, nothing. Did an UOA and that oil test showed elevated levels of silcon aka dirt! I switched back to Honda's filter, the dirt began accumulating on the dirty side and the newer UOA showed the silicon levels cut by about 2/3! The fram was definitely letting dirt come right into the engine with the illusion it was an actual working filter!
I think you could do some used oil analysis and I bet you'll be ok, but ya I agree, THANKS FRAM! no wonder they're bankrupt, kind of deserve it after selling junk.
