Recommended spark plugs for a WD?

Will Herring · Nov 9, 2014

I have a circa 52/53 WD (curved shifter WD but not a 45) and want to buy new plugs for it... What should I buy? Seems like recently people have talked up Autolite 295s or 303s as the best to go with. Is this still true? I have a distributor system on mine, since that seems to make a small difference.

A-C 45 are the best but been out of production for
quite a spell. I was an Autolite user but started
having issues with them when production moved to
China. Never did like Champions in an Allis but if
you have luck with them the number is J-8. I
started watching Ebay and picked up a few 8 count
boxes old stock AC45 for $35-40 and they work just
as good as they did years ago, my tractors love
them. That is actually the only plug I can
recommend at this time.
