I wanted bring this to attention. I spent some time yesterday talking to the service manager at Honda and he told me Honda will not warrentee any claim with a k&n. He said vehicles with large displacement throttle bodies will suck the filter dry of oil and allow the dirt to pass through easily. Regardless of the label on the filter they are not acceptable. I prefer them always have and was waiting for one to come out for the Pioneer however I wasn't aware of this being a factor and am use to dealers telling you to not buy them and usually it's because they can't sell you theirs over and over. I've since talked to a couple other trusted mechanics who also say the same thing as well as spending some time online looking it up with the exact same results. You could run it however the maintenance to keep them oiled far exceeds their usefulness and they can gum up the butterflies inside and allow dirt to stick. Figured I'd share this hoping others don't experience problems because of this.
