It's simple to adapt your breather line to the K&N, first off: make sure that your K&N will not impede on your rear hood shock ( filter too long).
Use a dremel and simply make a small 5/16" dia bore into the side (neoprene) neck of the filter. Then push in a 1/4 (pipe size) x 1/2" push over (hose nipple) fitting into the hole. Your vent hose will push right onto the nipple and your good to go. If you need to buy the right size hi-flow cone filter , with the adapter in it >> call me at 818-507-6937. These are properly sized for our MSDS kits and cost $50.00, adapter base not included.
As far as the hi flow air kits that we build, they must be worth something; the top podium finshers in POC orange group are all rolling with my filter kits, and Aase engines of course!
