Comments about K&N Replacement Air Filter:

Got this to go on my 2007 Honda Shadow Spirit 1100. Perfect fit. Comes with a self adhsive foam seal that you apply to the inside face of the airbox lid. Pull out your old filter, wipe down the surfaces and lid, install the seal, install the filter (make sure it seats so it flush to the top of the airbox. Reinstall the lid. Poof, not much simpler. I haven't had a chance to take it out for a ride yet but I'm looking forward to see if there is any gain in throttle response or power in the seat I can feel. I love K&N products and highly recommend!
