Do you have any preference when changing your oil on which filter you would use, genuine or aftermarket. I know you would be advised to use genuine if under warranty but after that period would you use aftermarket oil filters?
Lots use K&N as they have the nut on top to tighten/remove filter plus they are good, For what a filter costs I'd by oem Or k&n for piece of mind
I always use Hiflo filters. I get them trade price so cost me pence to buy. last one I bought cost me 68p I think
OEM for me had enough trying to cross over filters on my last bikes.Too small /too big.Under warranty it has got to be OEM.Not tried KN filters yet,will do when warranty runs out.
Only ever used OEM, but I can't see there being any problem using K&N as they wouldn't produce an inferior filter. More than there reputation is worth to do that.
TBH I have always shyed away from aftermarket in favour on O/E mainly to satisfy warranty issues if they might occur but after that period I would probably use aftermarket filters, K&N seem to be a popular brand from the comments received, maybe its to do with the hexagon nut on the to facilitate fitting but more so removal, I may give them a try on the next oil change. Thanks for all the comments.
