Had them for me to pick up the next day.still need parts for this crappy Focus of mine.
You got these for me before(from an old email):"-(4) AZFS22C OR
AZFS22(F4) spark plugs. I think the first name is the old name?"
Can you still get them? If so, you can go ahead an order them. Just
let me know when they're in.
Me and a guy here at work have a running joke, because anytime you walk in looking for a non-stock part, they still ask what kind of car you have, and if you have air conditioning.What ever you do, don't tell them what kind of car / engine you have or you'll never get them.
I don't know. I would think that you would want platinum plugs if you could get them in the right heat range. A lot of guys don't like plats because they need to be read differently than coppers, but I think you have a wideband, Pectel, datalogging and the knowledge to use it, so my guess is that the ability to be read is at or near the bottom of the list of features you desire in a plug. Plats last longer, especially under tough conditions. Why use a copper?Aren't the copper better for me, or is it only if you have nitrous? Also, I think they might be cheaper?
I just want the colder plugs, to avoid detonation, I know that.
Because we like using hard to find parts that were never designed to work on a Focus?
The last set I took out of the car, had at least 20,000 miles on them and they truly showed almost zero wear. Contrary to the OEM plugs that at 16,000 miles (boosted at 11,000) where the electrode on all four plugs was down to 25% of its original size. I could hardly believe that the car still ran.As for the spark plugs, copper conducts electricity much better than platinum, but it will "wear out" much faster. 20,000 miles on copper plugs sounds great from what I've read - I'd be happy with anything over 5,000.
