Spark Plugs

[Jim Phillips]

I am about to change out the plugs on my 8N and did a search and everybody recommends Autolite 437's. Kragen says they are no longer made and they recommended Autolite 85's as an alternate. YT doesn't list 437's either, so where are they available or should I just use the 85's.

Go to RockAuto.com, NAPA, external_link, O'Reillys, all of the usual suspects. Ask for it. You can also use Champion h12 (512) as well. I have had no trouble with them and will use them too.

But what plug is it? YT's page doesn't indicate and this forum has posts for a half a dozen different manufacturers and model types.

Look at the very last where it says AL437. AL = autolite.

Got it! Ex-military where part numbers had no bearing on what you were ordering!
