spark plugs
I have been using champion w-18 plugs for years but like the looks of the motorcraft plug. What heat range does the motocraft compare to champion? Would like the number...
Thanks , J.D. |

That would sure make a nice metal sign to hang on the garage wall. |

Tom, Several websites have these spark plug sign pixs and some or being sold as repop signs by Amazon and others. Here is a link to a nice garage clock: http://www.amazon.com/Vintage-Champi...ertising+signs |

JD 1931, someone posted a heat range chart for various spark plugs about a year ago. I don't know if you can find it by using the search feature above? |

Re: spark plugs
I don't think I've ever heard someone say they prefer the look of the motorcrafts.

Re: spark plugs
I have the w18s in my A. I have them because they were brand new in a junk engine I had. I don't think id run the 3x, not really a fan of $25 a plug.

Re: spark plugs
Thanks to Larry Brumfield for posting this a while back
HOTTER DOWN TO COLDER - Spark Plugs For those who may be interested, the following 7/8"-18 spark plugs will fit the Model A and were available as of a few years back. They are also not all the ones that I know of. Champion (hotter down to colder): W95D W89D W16Y W20 W18 W14 W10 W85N W80N Also the original 3X and W18 which Champion lists as norm. Also according to Champion, the W16Y is hotter than the W18 at low speed but cooler at high speeds over 5500 RPM....(over 5500 RPM? ... maybe Speedy ED J, Pete, George Miller, Dennis Pierce would be interested... maybe even Brent) Motorcraft (hotter down to colder): TT15 (the same as Champion W89D) TT10 (the same as Champion W14) TT8 (the same as Champion W14) TT4 (the same as Champion W10) Autolite: 3076 (the same as Champion W14 and Motorcraft TT10) Mopar (hotter down to colder): P-9-7S P-9-6S P-9-5S Prestolite (hotter down to colder) 78-10 78-8 Stitt (hotter down to colder) 137 BSP 197 147 B 13/10 Range is a key word when one speaks of heat range. Reading these Champion numbers is not real difficult. For example, W20 or W18, etc.: The W is the shell design and it always means 7/8-18. I should also add that Champion has made changes over time. For example a C-16C, used in many a Model A, starts with a C, BUT it is a 7/8-18 plug. It was discontinued about 1979 and replaced by the W16Y. There are many like this. The number is the heat range and the lower the cooler (unless other letters immediately follow, like Y for example, which depending on the letter or letters can change or affect the heat range): 1- 25 = Automotive and small engines 25 - 50 = Aviation 51 - 75 = High Performance 75 - 99 = Industrial and Special Applications Larry B.

Re: spark plugs
I've used motorcraft 3076 and found them to be great, and you can't beat the price.

BTW, does anyone know if the modern plugs, like TT10, have resistors? Doug
