Honda uses two very similar oil filters that they say are interswappable but there is a miniscule difference between them, the end cap (metal ) is flanged an extra 1mm outside dia. on the one for 4x4 atv use. I believe it either restricts flow or possibly creates a disturbance that may catch more particles? I honestly don't know but motorcycles and the 400 ex use the higher flow, non-flanged one.
motorcycle and 400 ex one is Honda= #kfo-315, hi flow= hf 113, K&N= kn-113
4x4 atv use one is hm5-a10, hi flow hf-112, kn112 but it will work if you can't get the other................
