Paul: I see what you mean. Where I live, city driving means a minute or two at the stop light is followed by a few minutes at 35mph or so. Easier on plugs, I guess. |

Great Article on NGK's and changing heat ranges in the recent FORZA. It's a keeper. Mike. |

well, NY city traffic is kinda stop and go...more on the stop side..so there is not much of an opportunity to keep the rev's up..I definately avoid lugging the engine...seems that the bp6's just didn't get hot enough to burn of the low speed loading up... |

I've got about 9000 miles on the bp6's, and they are working perfectly. I've never had a problem with them loading up in traffic. Carb car, no cats, Euro Ansa exhaust, Crane ignition, plugs gapped at about .028.
What rpm do you use in traffic? I stick to between 3K and 4K, as per my mechanic's recommendaton. |

the car was loading up in traffic and just wasn't running the way it used to when I bought it 10 years ago...after reading some of the posts and then looking at some of the service records I found that the bp5's were used..there was also an interesting article in the latest issue of Forza on plugs.
the car is a 78 gts with crane ignition, stock coils, no-cats, ansa euro exhaust, larger carb-jets.

Mitchell the 5 in NGK is a hotter plug. I did the same thing in my 308 and cured a multitude of problems. I also set the gap at .035. I also have the Accell H.V. coils. I made this change a year ago it has cured a rich problem and no plug fouling on short trips. Works great for me. |

Paul
What is the reason for you to go down 1 more heat range?

changed the NGK bp6s I had in this past weekend to bp5s and gapped them to .035 per the advice of f-chatters (car has crane ignition) What a difference...smooth consistant idle, lots of power...even sounds better...and didn't load up in traffic...Thanks everyone for the advice!!
