800 spark plugs

[Rog-i]

I know this must be an olddd question, but what is the best plugs to use in my 800 and 8n both are now 12v. Thanks

Actually, its not an odd question as it has been asked many times before. A lot of guys prefer the Autolite 437 or the Champion H12. Have fun with your tractor.

Don't use the Champion. Not a good match for a Ford engine. Autolite, Motorcraft, AC, anything but Champion.

I run Champion H-10's in my 1957 960 and have since it was new. I feel the Autolite 437's are somewhat on the hot side, don't need a hot plug especially here in FL.

I prefer autolite 437's.. but they are so hard to get here nowadays.. yet if I look around I can find the champion H12 ( 512 )

Sounder - rockauto.com - less than a buck a piece plus shipping. Just ordered 16 for the shelf. AB

Glad some of you get along with Champions. I've seen new Champion plugs, and yes they were the right number for engine, put in Ford engines and the engines wouldn't run worth two cents. When taken out and replaced by something else, the same engine ran like a top.
