Folks,

I am new to this board so please take it easy on me :)

Anyway, I have a 2000 S500 and I am thinking about changing its spark plugs myself since the car is over 8 years old eventhough it has only 40K miles on it. I just finish the oil change, brake flush, air/carbin filters replacements, MAF cleaning. I did spark plug change on my other 3 cars (Boxster, Honda, Lexus) so I know the routines but I hear the spark plug wires on this car are very hard to remove. So the question is what type of spark pkug plier do I need to get the job done without destroying the wires? There are several pliers out there and I don't know which one is best suite for this car.

Any advice/helps/pictures are appreciated.

Thank again.

First you are about 50 to 60K early on those plugs..

Secondly, I hope you were kidding about pliers for spark plugs..

With a normal spark plug socket and an assortment of extension, and swivels, you can remove all of the plugs on this car with ease..

Good luck.

The plug wires can be a little difficult to remove. It helps to remove the coils from the valve covers first with the single torx bolt on each. A 17mm open end wrench can be placed over each silver boot collar and pried against the valve cover. I recommend prying with one hand on the wrench and the other hand supporting the bottom of the plug boot because the tendency is for the wrench to pry the boot at an angle. Too much force will break the plug off. I've broken a plug but no problem. The spark plug wrench will still remove the broken plug since the metal body is still intact. Although not totally necessary, I use an anti-seize compound on the new plugs' threads and dielectric grease on the boots so everything will come off easier next time. Hope it helps.

the two on driver side close to passenger side are toughest to get to. the rest of them is ok.
