I bought some Mobile One full syn. to put in my Stang. And of course the Ford oil filter. I've allready got 38,000 miles on the car and was thinking maybe I should change the plugs too. I'm guessing they're right on top under what I think are the coils. Any advice on which ones to get, if I should bother, or something I need to know before I go to change them?

The coil packs are black and sit in between the intake and valve covers. And yes the spark plugs are underneath them. It is very easy to remove the coil packs and remove the plugs also.

That's what I thought, I looked around for a minute or two and it looked pretty easy and straight forward. I'll be getting to it this weekend. What's the gap anyway?

Some S197 owners have experienced problems removingtheir plugs. Recommend watchingvideo #26 in the following link in orderto possibly avoid the same problems.It's for the 5.4 L engine, but it has the same heads as the 4.6 L in the S197.

Thank you very much. That was very helpful. I don't think I'm going to change them. It runs great, and I don't think it's worth the possibilty of something going wrong.

You're welcome.
My intention was notto deter you from changing your plugs. Manyowners have successfully pulled the plugs on their S197's. I just wanted to make you aware ofthe problems thatcan possibly happen when you decide to do so, and what stepsyou cantake to hopefully prevent them.

In my experience, plugs should be changed at 75k in most normal situations, and that's one of those.. I'ld perfer to pay a pro 50 bux to do it for me. It's not worth the possibility of stripping the plug, or droping something into the cylinder .. or god knows what else can go wrong. Also, most of my cars have had atleast 1 plug rusted out.. which is never a good thing (usually older cars though)

If you are not having a problem I would not replace them. At least not tell 50,000 miles

The labor will be considerably more than $50 if the mechanic knows what's involved with the S197's.
2mechanics quoted meover $200 forlabor. They know.

Does anyone know if running colder plugs while still N/A does any good, I have some HT0 plugs I was going to use with a NOS system but sold the system, kept the plugs, should I sell them or install them? Benefits for running a colder plug ?


thanks
