Hijacked!
Spark plugs, which MotorCraft ones to buy?
SP432 or SP417???

[RF Overlord]

Stock replacement is SP432. Cooler for Trilogy cars is SP505. Never heard of an SP417, but the way Ford's numbering scheme works, that would be a hotter plug than stock.

Coils: motorcraft, dont get granatelli....lots of bad reviews.
Spark plugs: autolite, AP104....works for a na motor.

Are you sure it's a COP problem? Try cleaning the MAF, that may resolve.

Thanks Bud!
You can have your thread back now!

[Vortech347]

Also make sure they have a warrant before letting them under the hood.

Worst joke ever...

Another Hijack..... sorry.

List of spark plugs for a 4.6l DOHC:

Stock Heat Range
Autolite –104
Autolite Double Platinum – APP104
Autolite Iridium / Xtreme Performance – XP104
Champion Copper Plus – RS12YC
Champion Platinum Power – 3401
Champion Double Platinum – 7963
Champion Iridium – 9204
Bosch – BSH7571
Bosch Platinum – BSH4205
Bosch Platinum+2 – BSH4305
Bosch Platinum+4 – BSH4458
NGK V Power – TR55
NGK G Power Platinum – TR55GP
NGK Laser Platinum – PTR5C-13
NGK Irdium IX – TR55IX
AC Delco – R42LTS6
AC Delco Platinum – 41810

Colder Heat Range
NGK – TR6 (+1 colder)
Autolite Iridium / Xtreme Performance – XP103 (+1 colder)

FYI..........

• I'd never run Champion plugs in a Ford motor.
• All the plugs that have a gimmick are just that ... a gimmick aka: snake oil...
• Examples: Pulstar. Halo, DTS-i Triple Spark, E3, fire injector spark plugs,

Oh... before you ask, going to a colder plug will not change anything unless you have a tune to take advantage of the colder heat range.

Whats cheaper, spending $180 then another $240 a year later, or spending $240 and lasting 10 years.

Your call.

Stock replacement is SP432. Cooler for Trilogy cars is SP505.

So if I'm going to run a tune I should go with the SP505 vs SP432?

If your tune or tuner compensates for it... yes.

your are absolutely right, just sucks because it feels like you are throwing money at the car to fix a problem that exist but cannot be pinpointed.....ie if its not the ignition coil set, then spend more money on another part that "might" fix it. iac, egr...what else could it be lol.
