thedawnpatrol Posted March 16, 2016 Share Posted March 16, 2016 What spark plugs should I use in my 1941 Morris 6 cylinder engine ? Jules Quote Link to comment Share on other sites More sharing options...
goanna Posted March 17, 2016 Share Posted March 17, 2016 Hi This is a good read and it might help you . http://www.strappe.com/plugs.html From memory , you need the 18mm plugs for that OH engine. Some of the 18mm plugs have a tapered seat which you don't want . Mike Quote Link to comment Share on other sites More sharing options...
MatchFuzee Posted March 18, 2016 Share Posted March 18, 2016 You could try The Green Spark Plug Co:- http://www.gsparkplug.com/ignition/spark-plugs/18mm-diameter?sealtype=17 Quote Link to comment Share on other sites More sharing options...
Ivor Ramsden Posted March 19, 2016 Share Posted March 19, 2016 AC Sphinx 87S is one of the original fitments. The Green Spark Plug Co website, linked above by MatchFusee, lists them and cheaper equivalents. Quote Link to comment Share on other sites More sharing options...
