Champion X plugs can be taken apart to clean them when the foul, but they cost $35 each. The Champion plug that doesn't come apart are $15 each, but when they foul you either have to clean them with a plug cleaner or throw them away. Carburetor cleaner works too. The Motorcraft plug does not come apart but they only are $4.50 each. All three are good plugs. I use the Motorcraft, found them on Ebay for $2 each, when they foul, I throw them away.

Spark plug questions are like oil, everyone has their OP. I run old used Wards plugs, car runs great. Car ran fine on the replacement Motorcraft's also but it's a crap shoot if you can find a set that don't leak around the porcelain and body.
Most used Champions are just plain worn out. Plugs do wear out. You can take apart and clean but again a crap shoot to find new seals or have the old ones reseal.
If you are running 14MM with adapters and coils/magneto, get plugs that do not have a resister in them, the resisters do not like the un equal voltage from the magneto.

In general the plugs made back in the days when T's were being used as daily drivers are the best. I collected enough on eBay to last a lifetime. My rule is to never pay more than $5 for a plug. I've bought 10 - 15 new old stock Model T plugs for as little as $1 a plug. No, I don't want to sell any.

Some good info is here:

After mucking around with modern plugs for a couple of years, I've had the same set of Champion X's in my car since 2006. Initially, I used adapters to run a variety of modern plugs, because they had a much bigger heat range. I spent a whole lot of cash on various modern plugs and eventually found that with the original Champion X, the car started easier and idled smoother. Also, being a pull apart, and therefore serviceable, plug, you only pay the bigger price once.
Cheers,
Rob
