And unless you really enjoy physical pain (bloody knuckles), hire someone else to do the job. I started to do my daughter's '97 Explorer 4.0 V6 and said screw that.

It ain't that bad.

 

[Kyle Keller]

well unless your arms are toothpicks, you will probably have to take off the tire and go in throught the wheel well and its still a pain.

Use motorcraft plugs they say the Autolite are the same but something is different the motorcraft ones will last a lot longer, and seem to have smoother idle. I worked in a parts store for 4 years Motorcraft is the only thing I would use. also make sure if there platinum or double platinum get the same ones that Ford installed factory .

I have Denso Iridium. They work very well.

Changing them is not hard if you have the right tools.

I helped Jeff C install his during the Dyno Event at the LAP meet. I then helped Rodger install three plugs at the Huber Lunch during the LAP Meet.



They are not that hard to do. I have seen worse.

If you think that the Trac is hard, try changing out plugs on a mustang big block.

Mike I was just going to say the same thing. Had to losen the motor mounts and jack up the engine in my friends '68 Mustang just to see the plugs.

 

[Larry C]

How many miles are you guy recomending to change teh plus? What about the wires, do you need to chagne them?

 

[Tom Schindler]

Larry,



IIRC, recomended replacement is 100K miles, but I changed mine at about 60K miles. My brother-in-law's Explorer went 143,000 miles on the OE plugs.



It is up to you. I changed mine because I enjoy doing auto repair and I wanted to do it. It is ultimatly up to you, though I do not recomend going 143,000 miles on the OE plugs.

OK so I can wait on the plugs a while. I'm at 14k+ since the first of the year.



What about the wires?

Do the aftermarket wires help that much. I'll be getting a xCal2 soon also.
