Spark Plugs Navigator

Alternatives for the NGK plugs

You can buy NGK B8ES plugs almost everywhere, but I’d stick to a known dealer as there are cheap copies out there.  The manual says KLG FE80 or FE100.  Champion N3 is another choice. 

There’s another cross reference here:

Hi all, I’m doing a major service on my Navigator which I converted to the Pazon 12v electronic ignition about 18 months ago which has performed perfectly and transformed the bike.   Interestingly when I checked the NGK B8ES plugs (which I hadn’t used before) the centre electrodes were far more eroded than I have ever seen on a Navigator after only 2000 miles.   The mixture is spot on and the bike was running very nicely despite the wear.   I am wondering whether the excessive erosion is normal with this grade of NGK plug or is it a result of the ‘spare spark’ system which is sending a soak to both plugs every revolution of the engine?   To explore further I am going to try the Champion option next and see if they fair better.   Nick

Champion N3 - or - NGK B8ES - or - KLG FE80 or 100 - all good, more choices below
