So I had a Fram Ultra on my Accord 2.4 but it was giving me some louder than normal start up noise...I switched it to Pennzoil Ultra and Honda OEM A01 filter. No strange noises and the oil pressure light goes off sooner at start up. Also when I started it up after changing the oil it didnt knock at all like it did with the Fram Ultra, and the oil light went off sooner too. So it seems the Honda A01 filter does have better flow, but im still looking for something with better Filtration specs than Hondas 65% not too impressed with that and i fear that would catch up in the long run. More wear. So im looking into a Pure One 14610 or K$N. I hear the Puro has 99% at 40 microns...is this true? Also ive heard the K$N has a bad time with the ADBV as its nitrile, ive heard of these failing too soon. So Puro, K&N, or Honda oem A01 for next oil change? what do you guys think? also what are the specs for purolator and K$N?
