I just picked up a K&N air filter and when I went to install it found that the top ring was 2-3mm larger in diameter than the paper filter that was currently installed. As such it would not sit down into the air box and I couldn't secure the top of the air box because the bolts weren't long enough. I've already ordered a replacement to be sent to me but I was wondering; has anyone else had issues with the K&N filter and fitment?
