BogMonster Posted June 24, 2006 Share Posted June 24, 2006 Can anyone now move this to a Bosch NGK Champion etc plug pert number ? Come on now Don't be shy Nige Nige, That is what mine has and I am almost sure they are a different physical size so will rattle a bit in your spark plug holes. Will try and find one of my old ones tomorrow and check it against a "normal" one I know for sure the spanner is a lot smaller and I think the plug thread is too but wouldn't swear by that. The RC11thingy is a Champion plug number by the way, and IIRC they are the wrong side of 50 quid for a set this platinum stuff they are coated with doesn't come cheap On the plus side it starts immediately every time and runs like a sewing machine so I can vouch for the positive side of running non dizzy ignition Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted June 25, 2006 Author Share Posted June 25, 2006 Steve, Ta May well be the body of the plug is the skinny type with smaller "Spanner Size" but same thread and end for the cyl head. Need to do some research yet, but please do have a peek Nige Quote Link to comment Share on other sites More sharing options...
BogMonster Posted June 25, 2006 Share Posted June 25, 2006 OK here you go, on the left is a standard 3.9 plug Champion RN11YCC and on the right is the Champion RC11PYPB4 that fits my 4.0 (which has the "Thor" engine/Bosch engine management/four coil dizzyless ignition system) Everything else is smaller except the thread and reach which is identical so the good news is that they will physically fit According to the "spark plug bible" at work, the rest of the plug number is: R - resistor C - the physical dimensions 16mm head instead of 21mm; reach is 19mm and thread is 14mm same as the RN ones 11 - heat range PYPB - Platinum tipped electrodes with insulator projecting 1.5mm and tapered off ground electrode (same projection as the YCC except platinum) 4 - plug gap 1mm which I make 39 thou in the old money It says somewhere else that you mustn't adjust the plug gaps on these as jamming a feeler gauge in there will damage the platinum coating, and since that bit is what presumably costs £7 odd I guess you wouldn't want to do that Quote Link to comment Share on other sites More sharing options...
