I had ran a tank or 2 of bio that was lets say not the cleanest, which left some material that looked like someone had blown their nose in my tank. I mean it looked just like snot and boogers! I cleaned these off for the picture.
Nice to know I get some decent fuel otherwise. Most of the bio I have bought was super clean.
I was at 9-10" of restriction with B90 when I replaced this filter. It immediately dropped to only 3.5-4" with a new filter. Bio doesn't flow worth a crap through these oem duel pleats.
