Just my five-pennyworth on K&N filters. 
When I first started doing Full Monty installations, I used K&Ns but found that most needed to have the flange reduced with a Dremel to get them to fit in the airbox. Nothing major but an irritant. Nothing to do with owners mangling airboxes - just a manufacturing issue at K&N.
After a while, I switched to using BMC filters as these were supplied to me by Ivan's UK/EU agent back then. Very good quality, perfect fit.
If Ivan recommends DNA, listen to the man.
