"I've owned several K&Ns and they are easier to service. If you are buying a high performance filter for airflow, K&N is tops in this test." quote from the web link. It's a bit presumptuous to assert that I am going into this "blindly." That study was done with water, so he is making some assumptions when comparing H20 with air. I like the concept though, gets the ideas going. No air intake kit is made for this engine that I know of, so I may very likely keep things stock. thanks
