F355GTS Posted October 24, 2002 Share Posted October 24, 2002 Does anybody know the correct (or best) Spark Plugs to use for a 98 VHPD with KV6 TBs and Mems ECU? ta Mark Link to comment Share on other sites More sharing options...
Mike Bees Posted October 25, 2002 Share Posted October 25, 2002 'Road use' plugs as supplied by Minister are Champion RC6YCC. They work fine for me. Mike Link to comment Share on other sites More sharing options...
V7 SLR Posted October 25, 2002 Share Posted October 25, 2002 Yeah, whatever was supplied as standard I replaced when I was diagnosing my misfire (turned out to be ECU). The plugs I removed were in perfect condition after 12,000 miles, but I left the new ones in anyway. Never had a problem with plugs at all.

F355GTS Posted October 25, 2002 Author Share Posted October 25, 2002 Thanks Guys that's the ones that were in there and I fitted new last night Mark Link to comment Share on other sites More sharing options...
Steve-B Posted October 25, 2002 Share Posted October 25, 2002 I have discovered that from conversations with Nige, and checking the 1.8K manual, that the correct gaps are NOT .95-.98 but are .90. .90 is how they come out of the boxes FWIW.....steve I really want some HOTTER plugs, but am at a loss as to how/where/what they be. I've searched the guidebooks at Halfords, which were a load of pants IMHO..... Go team GBR ❗ Link to comment Share on other sites More sharing options...
Mike Bees Posted October 25, 2002 Share Posted October 25, 2002 Do you really want a hotter plug (why?)? I find you can use a cold-as-you-like plug in a K-series & they don't foul. Mike Link to comment Share on other sites More sharing options...
murph7355 Posted October 25, 2002 Share Posted October 25, 2002 Doesn't temperature inc. with the number on Champion (7 is hotter than a 6 etc) , and decrease with the number on NGK (6 is hotter than a 7 etc)? Link to comment Share on other sites More sharing options...

Peter Carmichael Posted October 28, 2002 Share Posted October 28, 2002 Champion's numbering is inconsistent. Link to comment Share on other sites More sharing options...
Peter Carmichael Posted October 28, 2002 Share Posted October 28, 2002 You do not want a hotter plug. Link to comment Share on other sites More sharing options...
Steve-B Posted October 28, 2002 Share Posted October 28, 2002 I have been informed that a hotter plug can offset altitude problems. 😳 wouldn't the same be true for just closing down the gaps a wee bit 🤔 scb Go team GBR ❗ Link to comment Share on other sites More sharing options...
