[VintageLambo] Re: which is the right NGK plug? 2 cents worth

I recommended the 7 range as a precaution to a new, hot engine. As for the "platinum" electrode, well, here"s my opinion: Several years ago one mfg came out with a "platinum" spark plug. There was millions spent on marketing hype, race promotion, track validation etc. The mfg actually increased their market share by a few tenths of a %, regardless that most of the plugs sold were of the non-platinum variety. As time went on, all mfg followed suit like a bunch of lemmings and nearly all offer a platinum type product now. I"ve tried(lemming that I am) Platinum plugs in various cars, boats and even in an airplane. I was generally unimpressed with the results over the larger arial density standard electrode. Although Pt has one of the lowest resistance coefficients of any metal, the amount of Pt actually on the tip of the electrode can be measure in angstroms, or perhaps even by counting the individual atoms. Another factor that dismays me is the fragility of the electrode. I"ve seen Pt plugs come out of a turbocharged boat engine with the electrode melted off as there is less metal mass to dissipate heat. Anyway, one man"s opinion is as bad as another. BP7ES can be bought at Pep Boys, if it"s too hot, change numbers. I"ve had a set in my Kawasaki jet ski for three seasons, and it runs like a champ, no fouling, which may be important for a car with new rings....
