Note: NGK plugs are no longer factory gapped. DO NOT GAP IRIDIUM PLUGS WITH A COIN OR DISC STYLE GAP TOOL. Attempting to gap Iridium plugs with any tool that contacts the center electrode will damage the electrode and void any warranty. Use a gap tool such as those combined with feeler gauges which has a fork or slotted prong that allows you to gently bend the 'L' shaped ground electrode to the proper gap. Most Harley models require a gap of .038 - .040 for electronic ignitions. Be sure to check your factory service manual. The manufacturer does not warranty broken or damaged center electrodes, so use extreme caution.
