Anthoop Posted February 9, 2015 Share Posted February 9, 2015 I guess sometimes a plug could be faulty straight out of the packet but you should not be going through plugs that fast. Many things will ruin a plug and by looking at the damaged plug you can often find an indication of why it blew....is the plug coil grey and distorted= lean/hot. Having the right plug in the engine is not really a matter of will it last...more will it provide the best performance for you/me/everybody on that day with that engine/car/fuel/exhaust/etc.driving it where and how we are. Having said that though, a cold plug has a thicker coil of wire than a hot plug and so will be more resilient.... You did not mention which engine you have (not that it makes much if any difference) nor the fuel you are using...but no matter...I can tell you that the OS8 will work fine in any scenario ( I have tried)....not ideal but works.

Dannymitchell506 Posted February 9, 2015 Author Share Posted February 9, 2015 The plug which was in it to begin with had been in it a fair while so I'm gonna say that it burnt out due to being used a lot , the second one burnt out after about 5/10 mins of running but as you said lean = hot so I'm thinking it burnt out due to the engine getting to hot because it began to smoke then died so I took the plug out and smoked started to come from inside. I think the problem might of been it running to lean. I'll just buy that plug you said and go from there. Thanks Quote Link to comment Share on other sites More sharing options...

lazkopat Posted February 10, 2015 Share Posted February 10, 2015 I've had a Hyper 21 engine which is now knackered and I use to run it on OS 8 glow plug with 20% opti fuel. The plug lasted for well over 6 months until it died out. I always use OS 8 plugs in my engines regardless of their sizes. Quote Link to comment Share on other sites More sharing options...
