Whats the part number\brand for the stock spark plugs?

[shanker]

I demodded and the NGKs are giving me problems and need to replace them. I tossed the stockers on accident.

I run AGSF22FM1 Motorcraft.

Are those the same ones as stock?

Depends on the build number.

'03 Sonic Blue coupe #621

AGSF32FM1
AGSF22FM1
AGSF12FM1

Goes from hotter to colder. Most likely you had AGSF22FM1. I would put those back in if you want to go back to a stocker.

shanker - I took my stock plugs out at 3200 miles... Have em all here.. let me know if you want them. (PM me)

no one had them in stock but the Autolite Platinum AP104s are listed as compatibal with the '03 Cobra. Will these be OK? What should I gap them at?

Thanks, Matt
