One was a dirt track engine and one was a Pro Stock 500 cube engine. Made a mess......

I used a System1 filter on my dirt track Sprint car back in the ninties. Never an issue with O rings, but did not filter as well as a NAPA (Wix) 1061. I sent my spare filter with my friend at the Sunoco lab when they did the oil filter tests I had mentioned.
Taking them apart for inspection & cleaning was easier & more convient than cutting a filter apart. Did not filter as well.
