I've been running a K&N oiled foam (more correctly: "oiled cotton gauze") air filter in the stock air box on my 2000 Sport for 10 years. I typically clean and re-oil it once a year and no more than 12,000 miles.
It's looking a bit ratty, and I worry about the controversy that this filter type doesn't really work as well as paper to protect against engine wear.
We've done this topic to thread-lock once before, but I'd like to revisit it and reconsider the pros and cons of paper versus foam filters considering some of the fresh outlooks we have on the forum these days.
Simplest question first, though: what is the automotive cross reference for air filter fitment in the stock air box (please consider both US and Euro)?
Ya'll boys play nice now . . .
