NGK and Denso both make good spark plugs. Most of the rest are sub-par or worse.

NGK: UR4
Denso: T14PR-U (resistor)
IW16 (Iridium)
Autolite: 26 (resistor)
AP26 (Platiunum)
APP (Double platinum)
Bosch: HR98C+ (resistor)
champion: RV17YC (resistor)

These are some, there are more.
I am using the AP 26 right now.
(to the dismay of others on this forum I,m
sure), I'd use the Bosch Plugs if I had a
choice.

Autolite plugs are now crap from China.
Champions have long been crap from America, who knows where they're made now.
Bosch = crap from China or Germany (see? Even the Germans can make crap!)

I strongly second using NGK or Denso.

Even 10 years ago I was having problems with Champion plugs. In cars that sit for a couple of months without running, the car would miss and run terrible. The plugs looked fine but just didn't work.

I would even use AC plugs after NKG or Denso, but since I have not used anything but NGK for the last 4 years I am not sure what they are like anymore.

Along the same line I have been only using NTK oxygen sensors as well. They really seem to be the best.
