slowrider Posted April 26, 2023 Share Posted April 26, 2023 Bought the electronic ignition for my 199B, last year 350 and noticed the it needs a spark plug that has the threads on top instead of the modern style plug for the boot to fit, I am using an NGK BPR4ES. Is there a plug that will work with this boot or do I need to convert the boot? Quote Link to comment Share on other sites More sharing options...

faussy Posted April 27, 2023 Share Posted April 27, 2023 You have a plug with a solid terminal. You can get the same plug either threaded or with a removable nut, no need to change the heat range if you dont want to Quote Link to comment Share on other sites More sharing options...
