Automotive engine air filter - Foam
Automotive engine air filter - Foam
(OP)
Hi there folks.
I had a question regarding automotive foam engine air filters. I was wondering if anyone here had any practical experience
working with foam air filters. My question is what PPI (pores per inch) would be most effective at both filtration and flow. Im thinking a 2 stage filter. I understand the more you flow the less you filter and vise versa but there has to be a sweet spot.
Thanks for any information you may offer.

Industrial engines in commercial and high end lawn care and offroad equipment sometimes use an oiled coarse foam prefilter with a paper air filter behind. the one on our mower keeps the intake tract nice and clean. I can not say the same for the big name oiled cloth filter i tried on my old dirt bike. That experience was similar to a few bike tuners on various internet bulletin boards. I now use a Wix paper filter for some 80s GM passenger car, but don't ride very much either.
