Bobtaylor Posted May 10, 2021 Report Share Posted May 10, 2021 Hi, any suggestions please for the alternative to Champion N-9Y. An internet site lists the NGK alternative as BP6ES. I have just looked at my car and it has NGK 5E fitted? Bob Link to comment Share on other sites More sharing options...

I did try Champion N9Y, but found the car didn't enjoy running on choke with them. Gully Link to comment Share on other sites More sharing options...
johny Posted May 10, 2021 Report Share Posted May 10, 2021 The 5 is a hotter running plug so do they look a bit cooked (white) or do you get run on/pinking? If so the 6 will help but might foul up more easily and also reduce igniting effectiveness... Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 10, 2021 Report Share Posted May 10, 2021 w78 bosch is getting some good reviews NGK have changed their ceramic protection, its been getting problems on carburettor cars recently there a good few post on here about plugs . fouling /misires etc the search box ( up top )will find lots of comments suggest you do not get any make with a R resistive suffix that will reduce your HT spark BP6ES is the std ngk replacement for a vitesse Pete Link to comment Share on other sites More sharing options...
Nigel Clark Posted May 11, 2021 Report Share Posted May 11, 2021 I'm a big fan of multi electrode plugs in our engines, but unlike Pete I've never found any problem with resistive versions. Bosch WR78 or NGK BUR6ET are widely available and from my experience work well, better than standard plugs. There's more info in earlier threads on this forum.
