Which oil filter?

[bananaman]

I know i've seen it on here somewhere but can't find it, doh....
My dealer's hr and half away, thinking k&n oil filter as they are more readily available. Know there was a discussion re the right one but which one was it lol. Is there such a thing as a bad filter nowadays? 2010 if it makes a difference. Thanks!!

K&N get a bad press although I don't know why. I use Hi-Flo or try www.motorworks.co.uk who will send you a nice Mahle one
