spark plugs?

My 1930 4-07 Durant has AC 78S spark plugs in it. They cross reference about three times to come up with a current plug and I'm not too sure about that!

Can anyone give me a plug number, Champion or AC, which is current and will do the job in my W-8??

Thanks ... RonJ

Hi Ron...

Your Model 407 four cylinder should take a Champion plug like the Model A Ford The old Champion number is W-16Y the new number is 561

The Motorcraft number is TT 10

If you can't find them localy I do have both of them in stock

I think the original plug was a Champiom C-4. It was the kind that you could take a part and had a brass cap over the end of the top the porclain at the spark plug wire end. Sometimes you can still find these at flea markets.


Re: spark plugs?

Hi Bob...

The old take apart style Champion plug is still available. Mostly just used for show cars because of the cost.

I do keep these in stock if anyone is interested....

Re: spark plugs?

Crusing this site I see info on Ron's 407 orig had C4 Champion's.
What would 22AA 614 have for the 32. I found some Champion 7 and 7a's in the pocket behind the seat that will never see a motor again, but the car has Autolight Transport BT8's in the head presently and been there over 45 yrs I assume. I assume Chanp 7 was the 6 cyl version ??

Hi Norm:
The Champion C7 is the old original. You can also use Champion D16 which I believe are still available.
