I have a Lightspeed III ignition and have been using Denso (5312) IK27 plugs. I noticed the NGK BR8ES being used by other electronic ignitions. The NGK are much less expensive. Are these the same heat range and acceptable to use with the Lightspeed? The Densos are the only ones listed on the Lightspeed website.
