I'll second this experience. I have K&N filters in all my vehicles (including my 1995 Pathfinder and our daughter's 2001 Pathfinder. I've never had an issue, but I'm careful to not overdo the "oil" when I clean and recharge them. I have a 1997 F150 5.4 with 250,000 miles, which has had a K&N filter since I purchased it in 1998. No issues at all.
