How many miles did you log on these plugs when you pulled them? How did they look? How was the gap?

Is it a good idea to change them on our engines stone cold?That's the ONLY time to change plugs in an aluminium-head engine...

Actually it's highly recommended that you change the plugs ONLY when the engine is stone cold (hasn't been run in AWHILE).

Please post pics or report the condition of your stock plugs when you get a chance!

Just put in my NGK T55 plugs Sunday at 22000 miles had just a frosted appearance on the tips and electrods. Gap was around .52 but 3rd cyl. had a .55 though but it was the only one. I gapped all the NGK's at .52 probably will gap them to .42/.45 when I get my Trilogy on after I get the car payed off.

I thought the gap for Trilogy was .032-.035 better check.

Sounds like you have some time:D Me 2

I would hate to let Ford credit get back a Torque/Monster, after I have got the payoff down to almost see-level:P

I'm not qualified to reply here, but I am curious. Why do you ask?

BlackHole: Sounds like the stock plugs fared pretty well? Any erosion on the electrode tips?

What plugs came out of your Marauder? AGSF-32WM or another type?

Mine are AWSF-32EM's And no erosion even with about 5,000 miles added after I installed the 4.10 gears/Throttle body/and JDM Super chip

Well when I changed the Lightning Plugs to NGK TR6's I gapped them to .42 per what other tuners suggested Johnny Lightning and Jim D'Amore owner of JDM Enginering. As the blocks are very similar except for the deck hight. And the DOHC heads on the 4.6L
