I've installed K&N air filters in all our Hondas. I'd wait before I put it into our new HCH. It only has 300 miles on it and I want to get use to it "as is" first. But eventually, if K&N produces an air filter for it, (right now it only has oil filters for this model), I'll be installing it, plus changing over to 0w20 synthetic (if I can find it).
