I rec'd an email today regarding the recall of K&N Oil Filters models KN-204 & KN-204C manufactured between March 2016 thru September 2016. Apparently some have exhibited leaking at the nut welded on the top for easy removal. Fortunately for me, I either didn't get one in that range or replaced it since, as my date code didn't fall in that range. If any of you use K&N oil filters, you may wanna check this out. https://static.nhtsa.gov/odi/rcl/2017/RCMN-17E044-1798.pdf
