Champion 7989 Spark Plugs
I just recieved my champion plugs and learned they are not one piece as I had heard they were. Look at this photo. In the groove to the right of the threads there is a bluish color. This is heat from the laser welding process that mated the plug body to the plug extention.
Guess these aren't a better choice after all.
FWIW, the set I ordered from RockAuto are junk. 2 have welds that are clearly over powered and are probably weak. 1 had a cracked ceramic body (electrode end) from being dropped. Another has the ground strap that was is mounted off centered. Clearly these Made In Mexico spark plugs are GARBAGE.

Just check them every 15-20,000 miles, just as you would with a Brisk, because they are more conventional and subject to gap wear. The Champions have one advantage over Brisk - they last longer. The Brisk plugs use a silver ground strap. Its very good as far as conductivity but it wears faster. I don't have any hard data, but I've heard the Brisks are good for about 25K max. The Champions likely last a lot longer. Either way, its better than Autolite/Motorcraft plugs. If the vehicle is built with supercharger, turbocharger, NOS, etc., Brisk is the only solution outside of Autolite HT0s because the Champions are standard temps. My next plug change I'm putting in Brisk plugs rather than HT0s.

Motorcraft carb/intake/maf cleaner or Kroil. Funny thing... Ford used to recommend Kroil (which is the best damn penatrant/cleaner I've used) and I guess they figured out if they recommended their own product they could make some extra money off this!
When I change mine (more often than most because they are subject to more extreme conditions under boost) I soak them overnight, then again 15-20 minutes prior to the job.

Defective Champion Plug
This past weekend, I was on a road gig with my band, and we started having misfires. After leaving it to a shop, and renting a car to get to the gig, I find out the culprit was a defective brand new (installed for 2 months) Champion 7989 spark plug. The plug was changed. Today I returned the rental in Gulfport, MS, picked up the truck, and drove home with no problems.
I bought the truck only two months ago, and I spoke to the mechanic that worked on it for the used car lot that sold it to me. He explained that they took the truck in with a cylinder missing, and he changed the spark plugs and fuel pump, and now it runs fine (which it did.) He went on about how the Champion plugs are great... they'll last 100K miles and will never break in the cylinder head like the factory ones, which prompted him to purchase a $600 removal tool, etc, etc.
