This might be a stupid question but I've just bought a pair of K&N filters for the 12
I got these way cheaper than standard one's , I've just put them in and they will not fit the way they are suppost to.
I had to put them in backwards to what they reccomend. The filter has a front side but will not fit , Turned around 180 degs.they fit fine.
Has anyone else had a similar problem with these filters and will it affect air flow at all ?
