JamesJDMwagon Posted July 2, 2016 Share Posted July 2, 2016 Hi guys just wanted someone's else's opinion on my plugs. I think the cars leaning out on boost it drives nicely the plugs are pfr6b Quote Link to comment Share on other sites More sharing options...
JamesJDMwagon Posted July 2, 2016 Author Share Posted July 2, 2016 Plugs too hot maybe try some 5's? Quote Link to comment Share on other sites More sharing options...
Piggysniffer Posted July 2, 2016 Share Posted July 2, 2016 Be interesting to see what people in the know say, they look about the same colour as my hawk ones, but yours have a bit of a pickled effect on the ceramic 1 Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted July 2, 2016 Share Posted July 2, 2016 Bit difficult to say if they are running too hot but I'd say it's certainly not over fuelling as they're not "sooty" Don't put 5's in as they're colder running than the 6's , most run ngk heat 7's on modified scoobs and close the gaps up a bit if running more than a bar of boost . If it's not broke .....upgrade it 😊 1 Quote Link to comment Share on other sites More sharing options...

I think sevens would make the problem worse as they are hotter. Happy to give them a try though. Got a bit of hesitation what boost comes in hard at 4K. What gap would you recommend? As I'm going to clean them up and slap them in until I can find the right heat range. Thanks for the reply guys 😊 Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted July 2, 2016 Share Posted July 2, 2016 I think I gapped mine to 6.5 instead of 7 . Changing the plugs for colder ones won't make the engine run any colder , if anything they'll probably make it run worse and possibly make them crack or fail . If it's not broke .....upgrade it 😊 Quote Link to comment Share on other sites More sharing options...
JamesJDMwagon Posted July 2, 2016 Author Share Posted July 2, 2016 Perhaps it's a little too advanced (timing) yeah think I'll stay with 6's for now. yeah I'm just gaping them down to .65 . I may give 7's a try see if that helps. Im trying too lose so of the hesitation when boost comes on, it revs out nicely thought plugs might be an issue they where gaped to .75 just now when I measured them really appreciate the help 😊 1 Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted July 2, 2016 Share Posted July 2, 2016 No problem bud, classics are known to "blow" the spark out when running extra boost and sometimes a smaller gap can rectify this (if it's a minor misfire) . If it's a v1/v2 a newage coil pack conversion is another option to increase spark strength [emoji6] If it's not broke .....upgrade it 😊 1 Quote Link to comment Share on other sites More sharing options...

I just want to get it running right but I don't think that's going to happen without a proper ecu. When its at 11 psi it's really bad hesitation but at 12-13 it's a lot better but not quite right Quote Link to comment Share on other sites More sharing options...
