DOH!!! I saw this response in the digest after I sent the
last one. Plus I just now remember that I didn't change the
subject before sending. Sorry!!!
I do not have the plugs that came out as I changed them over
30K miles ago. When I got them the guy at Napa said the
Autolite APP5224 was the manufacturer recommended direct
replacement. We had a brief discussion regarding plat and
non-plat and he said that the platinum was what was
recommended. I think the concensus on the list at the time
was that the platinum plugs allow you to get the advertised
100K miles between services.
I thought what I took out were platinums but I can't be sure
now.
The sticker under the hood says RC12MCC4. I don't know if
that is a plat plug or not. The owners manual says to refer
to the sticker under the hood.
Is there anyone with a FSM that can verify this? Can anyone
explain WHY a platinum plug would be bad for the 4.7 ?? And
if there is some reason that the platinum plug is bad, then
wouldn't all the other dip-stick one-off plugs with multiple
electrodes and tungsten encrusted kiniblin' pins be just as
bad???
Not tryin to attack anyone here... I just need to know if I
have to be buyin' plugs SOON as these have been in mine for
3 years now..... But it still runs great!
