.035 Does this car have the tube style head or the peanut plug head. If it has the tube style head use Autolite 985 or NGK ZFR5N extended nose plugs. |

Champion plugs suck. Use the extended nose plugs. They are much more efficient. I am not that good at explaining computer stuff but here is a page that explains more about uploading pictures. Wish I could be of help, but I am a car guy not a computer guy (what is a spreadsheet?). |

I replaced the Champions in my '64 with the Autolite 985's. It was running well with the Champions, but the high-mileage engine would foul them and at start-up there would be intermittent missing until the engine warmed up. Now it still misses when cold, but also has intermittent missing when warm. . I'm not knocking any plug, but in my experience, Champions are as good, or better than anything else I've used, and I'll be going back to them next time. |

Use the special extended-nose NGK plug number ZFR5N gapped at 0.040" if everything in your ignition system is in tip-top shape, 0.035" if you tend to let it slide a little. Remove the metal ring-washers from the spark plugs before installation. Note the ZFR5N plugs require a smaller, 5/8"-hex plug socket to install than the standard plugs will require to remove. The NGKs are a better-quality plug than the Autolites, which are still tolerable. The Champion equivalent is RN13LYC, but quality and durability are poorer. 0.090" mill should definitely not affect ability to safely run ZFR5N. |

Is there a 1 or 2 step colder plug than the 985? or ZFR5N? |
