spark plugs

steve19438 · Apr 2, 2015

presently one of my 35's has autolite 3116's installed. I have a bunch of new autolite 437's left over from my ford days. would the 437's be a ok swap for the 3116's?
thanks.

Don't the Ford plugs have a tapered seat, not to be used if the head needs a plug gasket like 386, 388, and 3116 has..

looks flat to me

Autolite's website says:

3116: 18mm thread diameter
437: 14mm thread diameter

I have used 3116 autolite plugs in my TO35 for years.

Best plug I have found for the old tractor.
