just a heads up guys.

09/04/03 > 04/05/04 2.3's used the 22 series motorcraft plugs from the factory. i believe these would equate to the 103's.

04/05/04 and newer 2.3's used the 32 series motorcraft plugs from the factory. i believe these would equate to the 104's.

being that my zts was an early model, the only benefit from changing plugs would be to keep the car running normal. i have about 87k on the originals, and there is a minimal rough idle, but nothing i think anyone else would notice. i think i will just replace with oem plugs since i get them for 10% over cost being an employee.

104s are the recommended heat range for the 2.3, but most performance-oriented people go one step colder with the 103. The tuning lead of this site (Tom) recommends the AR103s, which have a cut back electrode, allowing for more exposure for the spark.

103's are stock in the early 2.3's, as noted in my notes above, so going to 104's doesn't seem like a smart move.

A bit off topic:
I have gapped my AR103 to 0.065 a few days back. The engine behaved beautifully, until this one time I needed to reach about 5k while the engine was still cold; it stalled, and I've decided to go back to .060.
One thing I've noticed while gapping it on the first time, was some oil on the threads of two of the plugs. It did not look too suspicious to me then, so I simply wiped the threads off of the oil and put them back in.
But,
Today, I found out that the same two plugs are again covered in oil.
Dose anyone have any insights on the issue ?

Thanks!

The info is actually from Turbo Tom, not me. He is generally noted as the guru of the focus, as he has his own dyno and has done countless tests. He likes the AR103, not the regular 103s. Maybe the cutback electrode is why he says to do the step colder, not sure. I know that he (way back) ran a ton of tests and found that the 103 gapped .055-.060 yielded the best HP.

I defer to him on the subject, though I myself ran a LOT of tests on plugs...take a look at my old threads.

I run ar94s, but those are special, and not everyone here can run them.

In my experience when gapping, every point matters.

Thanks!
Valve Cover or Head Gasket Possibly? How many miles on the engine? Is the plug itself fouled or are you seeing it in the threads only? Less likely possibilities would be worn piston rings.
