RE: Stock plug question.
i just got the oe plug autolit and they are copper, lifespan hard to say depends on the driving conditions you have

RE: Stock plug question.
Several unique styles of enhanced spark plugs are produced for 4.6L (4V) engines. Each style is identified by the part number letters.
- AWSF-32E indicates the center electrode is enhanced with platinum and are used in cylinders 5, 6, 7, & 8 of the engine.
- AWSF-32EG indicates the ground (side) electrode is enhanced with platinum and are used in cylinders 1, 2, 3, & 4 of the engine.
- AWSF-32EE indicates platinum enhancement on both the ground (side) and center electrode. These EE spark plugs are the service replacement for all cylinders of the engine.
The AWSFA-12C is a colder plug, it is copper and helps prevent knocking.

RE: Stock plug question.
the "12" is two steps colder, the "22" is one step colder. The different plugs on different sides of the engine i believe has to do with different voltage used to fire them. one side was negative voltage and one side was positive voltage. i think.

Why were different plugs used in different cylinders? How many steps "colder" are the copper plugs, and do they affect drivability at all?
[/div]
The factory plugs probaly came that way to save money, platinum is $$$$
If you don't drive aggressive then the colder plugs probably wont make any difference. I think you could run into drivability issues if you are not aggressive, they may carbon foul. You can also go for the thin wire Lighting platinum plugs. They are colder, have the durability of platinum, and I believe the thinner electrode should help burn off carbon better.

RE: Stock plug question.
The copper plugs are a better way to go if you dont mind changing them more often. They conduct electricity much better. The only advantage to a platnum plug is that they can go like 100k before you replace them.
If quizzes are quizzical, what are tests?

I would not run 2 step colder plugs on a NA application...

I agree. I chaged the AWSFA-12C plugs today after having them for about 25k miles. They look great:
