Spark plug question

An electrode is a conductor through which electric current is passed.
Therefore,, there is both a center electrode and ground electrode on a spark plug. If both were not electrodes, the plug would not work.

I read some interesting things on multi-electrode plugs that bares mentioning here too:
1) Depending on the head design and sparkplug location, multielectrode plugs can actually disturb the combustion gas flow adversely degrading performance. Not sure if this would apply to the P-head design.
2) The extra metal of three more electrode can absorb and retain more heat, thus increasing chance of detonation.
Food for thought. I say use what P recommends.

That's where the companies focused the most attention to like the platinum plugs.

The industry's official name of what you call the "grounding strap" is "ground electrode" From Champion to Bosch. You need to move outside your "circle" more often.

Have fun changing those plugs! It's close to time to change mine again and I'm not looking forward to it. Just make sure you have lots of patience and no place to drive the car for a least a few hours. Magnetic socket and extensions/swivels are a good idea also.

I bought the recommended KD swivel socket set w/ magnets - I'm ready!! I figure I'll do the plugs with the car in the garage, so it can be worked on in stages, even if it's night or raining outside.

I need to do this soon too. What's this magnetic socket I keep hearing about? I assume Suncoast or Pelican has it?

Haa! You guys are pretty funny. I can see both sides of your stories, and being an EE, I should have been super specific and said "multi ground-electrode".

Drop the exhaust cans and the plugs are cake to change.

Which takes longer, dropping the exhaust cans or fighting the plugs? As I remember, my problem was the extension wanted to let go of the socket, leaving me with the socket attached to the tightened spark plug. That was a real pain.
Once all the skin was off my elbows and knuckles, the physical pain wasn't that bad.
