Steve Priest Posted September 14, 2016 Report Share Posted September 14, 2016 I spotted and bought a few sets of these from eBay - 4 packs of NGK BP6HS: http://r.ebay.com/9A0UJw They're clearly NOS but no idea how old. I know you can get new ones for a similar price but I quite like the fact that they list Triumph 2 - 4 on the back (and specify the gap). Not bad for £4.99 inc delivery. Cheers, Steve Quote Link to post Share on other sites

RobH Posted September 15, 2016 Report Share Posted September 15, 2016 There was chat some time ago on another forum, about NOS spark-plugs degrading while in long term storage. It was reported that advice from one of the largest manufacturers said the plating on the metal parts can oxidise/corrode which affects the seal with the insulator and possibly the electrical properties. Also in a suppressed plug the carbon resistor can degrade. This was followed, of course, by a fair selection of conflicting good and bad experiences from various contributors so the jury is still out I guess. Worth bearing in mind though.

Shall keep my set as spares & see what other comments turn up. At a fiver not a great loss if they have degraded. Quote Link to post Share on other sites
