I have a set of vintage 1933/34 v8 spark plugs. I want to clean them and test them. The new plugs just do not have the same appearance. Strange but there are some really nice model A reproduction plugs that look great and work perfect but these are not for a v8, but only for a model A and Model B 4 cylinder ford engines. What is the best way to clean up these old plugs and test them?

If you have one of these you can blast them but I recommend using light air as you can over blast them and loose the seal that is deep within the plug.
If you don't have one, well, you can use a bit of your favorite solvent and soft brush to get them clean.You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command! -

Do you think soaking old spark plugs in this stuff would clean them?You do not have permission to view this gallery.

If you can't sand blast them, try spraying with carburetor cleaner and blowing them off. I have also hit them on a wire wheel, just be careful of the porcelain3~ Tudor's & 1~ Coupe

I'm spraying the spark heads with wd40 and soaking the heads in MMO, it seem to be dissolving the carbon, I will also brush with a brass wire brush. The ceramic bodies, I am cleaning with Lacquer thinner..They are getting real clean. Now these plugs are supposed to be able to be taken apart? Afraid to do that because of their age, thing may crack?Comment

I would glass bead them. Protect the external porcelain from any media. Blast the electrodes as well, but don't shoot up into the hollow, aim your gun at a 90 degree angle. Then when clean, use a cold gun blue treatment to blacken the metal.Comment

I'm a little confused! I see Autolites, Motorcraft, two models of Champions, plus 14mm plugs that apparently require adapters. Then there are plugs with slip on connectors and plugs with knurled brass nut connectors. Prices for these plugs run the gamut from $4.99 to $40.00
Could someone explain what the practical differences are? Or at least tell me which plugs you use and why?

What spark plugs are you guys running and where is the best place to order some?08-29-2017, 03:39 PM -
just what were the spark plugs that were in the engines when they rolled off the assembly line?07-10-2022, 08:23 AM -
I am currently using these Autolite 3076 spark plugs. They are running dry and black. I have read/seen/heard that perhaps a hotter burning spark plug would work better.
Thoughts? Advice? Recommendations?

I know they are not original to the model A, but Splitdorf spark plugs were very popular back in the day. The correct model A plug is a #8. I'm curious to know - does anyone runs them in an A model?
I have a long Splitdorf history so to speak. Long ago, I used to restore Splitdorf generators used on motorcycles of the teens - 1920s. I used to run Splitdorf plugs in my antique motorcycles...04-17-2022, 06:57 AM -

Just pulled the plugs after the grandfather mountain tour 900+ miles and the porcelain is as white as snow. TT-10 plugs, car ran great. Added 4 oz MMO per fill up. Not enough miles for the tanning or am I running lean? Also, how many times should you re-use the copper spark plug gaskets?08-02-2020, 09:27 AM -
hi can you tell me if these spark plugs are for the Ford A?
Thank you09-07-2018, 05:05 PM
