Arne Posted June 26, 2014 Share #2 Posted June 26, 2014 The only important part here is the coil. If your coil is hotter than stock, you can use the wide-gap version of the stock plugs. I ran BP6ES-11 with Pertronix and a Crane PS-20 coil. Link to comment Share on other sites More sharing options...
Jarvo2 Posted June 26, 2014 Share #3 Posted June 26, 2014 I just upgraded to NGK (7133) BPR6ES-11 and have a Pertronix...I run much better now. Its more the spark plug gap than the plug in this case. The old points needed a smaller gap, where as the electronic ignition fires best with a wider gap. Link to comment Share on other sites More sharing options...
