Never used anything other than NGK BP5ES, never had an issue.Paul - 3 projects, 1 breaker - garage built and housing 2 white Stags. One runs, one doesn't -
... me too on various Triumphs, and very resonably priced at Green Spark Plug Company Ltd https://www.gsparkplug.com/1x-ngk-co...p5es-6511.html - £2.16 inc VAT (on 06/05/2024).Comment

I’m another NGK BP5ES, and have always used ngk on all my classics. I tried a few fancy priced ones years ago but the copper core seems to suit these older engines well.Terry Hunt, Wilmington Delaware

champion spark plugs are fine, so long as they aren’t fitted to an engine.
+1 for genuine NGK

+ another for NGK, never had any issues with BP5ES (now using BPR5ES since going EFI).
Just be very careful if you buy them cheap off eBay, they'll quite likely be fakes.Comment
