|05focusST91||I just replaced my autolite xp plugs back to motorcraft iridium's, WAY better. Cleaner/smoother idle. And the idle is even a bit quieter.|

Wasn't expecting to see the oil on a 36K mile car!
You had the crunching noise too?
All of the oil in the plug wells drained into the cylinders when I removed the plugs. Made quite a puff of blue smoke when starting it up!

They made a scary crunching noise when I took them out ... I thought I stripped the threads!
Wasn't that bad actually, by far the easiest spark plug change I have ever done! The car idles much smoother now and I have a lot of power back under 3500RPM. There's a hill that I used to be able to go up in 5th gear that I had to downshift the last year or so. Now it seems to have all of it's power back.
Only concerning thing was the spark plug wells for cylinders 2 and 3 were filled with oil. Blew out a puff of smoke on startup!

I've changed spark plugs a million times on engines with cast iron heads. Just a bit worried about trying on Aluminum.
Figure if I do it while the car is still only a few years old, I will be less likely to have problems.

|Dukttape||I've done mine twice now all I do is use a spark plug socket, 6" extention (only one I have) and a regular socket wrench and just run them until it tightens up and give it a tug to firm it up. Don't worry to much about stripping it unless your going to HeMan them in.|

My car is going to be hitting 36K within the next few weeks. I think I am going to be changing the plugs on it. I have never had a vehicle with 100K plugs that looked good at 40K miles.
I'm afraid to change them though as they are on an aluminum head.
How likely is it that I will strip the head. I'm planning on threading them on with a fuel line, tightening them by finger, then just doing 1/16 of a turn to snug them up.

|bile0026||Put in the AR103's over the weekend and I have to say, it does feel a bit more peppy and my idle is much better especially with the A/C on. Before the change I installed the Massive dogbone mount and would get a rough idle but very minimal now! Very impressed. Now we'll see how the MPG does.|
