      What modern day spark plugs are you guys using in a Perfo engine with electronic ignition?

        I am using these – http://www.cas-shop.nl/en/spark-plug-ta-eyquem.html?search=spark

        EYQUEM 457388

        But not with electronic ignition though (it doesn’t matter with or without)

            Nigel,
            I use Champion H10 with a 123 unit in the Roadster.

            CTA Sweden suggest: Marchal 5N, NGK BP6HS, Champion H10 or K.L.G. F 50

            However no mention is made of the ignition type See: http://traction-owners.co.uk/members_only/tech/Technical_data-11BL_BN.htm

            I tried to cross-reference the suppliers compatibility charts but quickly found that they “diverged” and didn’t tie up!

              I have a 123 dizzy fitted to my Perfo engined car (flat top pistons) and run EYQUEM N 43 F3+1 plugs which I bought from CTA

              They are circa 2mm longer than NGK etc. so sit that touch further into the combustion area. Car starts great and runs quieter and cleaner than NGK BP5HS or BP6HS

                OK,
                The Roadster has domed pistons, so sounds like they wouldn’t be suitable for me.

                I tried to get some of the 4 electrode Bosh’s but they are slightly longer (probably similar tot the YQUEM’s).
