The OEM air filter from my Camry is made of cellulose media. Laterly I found that almost all brands of air filters (Purolater, STP, Fram, Denso) for my car are made of cellulose and quality wise they seems to be identical. Yesterday, I picked up the last Fram air filter that is made of paper (new old stock, maybe, or someone returned?) where the rest of the regular air filter from Fram have shifted to cellulose media.
I am wondering which media provides the best result for air flow, since this is the first time that I use a non-cellulose media air filter.
