Arggghhhhh simple tune up on a gasser and the plug boots are stuck on with gorilla glue!!!!!!!!!!!!!!!!!!!!

I thought I was supposed to turn them 45-90 degrees and they would pop right off, I cannot believe how stuck they are. Help me before I break the wires.

There is a special tool to remove the plug wires without damage, basically modified pliers. The wires are pulled off, turning them does nothing.

Pliers are not the issue, I can get enough grip, problem is that it is not releasing the plug. The rubber boot on the number 1 cylinder is already torn, I assume from a previous ham fisted operator such as myself.

Give us a clue on which car you're talking about.

Sorry, its a 300SEL, I have wide open access to the plugs and can get a good grip on the boot, I tried twisting it back and forth and jiggling while I was pulling on it.

Also I sprayed some penetrating lube down there as well.

I had the same issue with my 95 SL500. You need to get a good grip on the boot a give a quick tug. Once you get them off, make sure you put fresh Di-electic grease in the boot so next time they will just pull off.

MB tool #110 589 01 01 00 (Hazet #2771) is a 17mm double open-ended wrench that is placed UNDER the boot and then levered to lift the boot up from the spark plug.

This is what I use, works good for me.

Part # 103 589 00 37 00

I use a narrow-tip small visegrips to latch onto the metal boot flange. Plenty of safe leverage with this.

Whats the story with the platinum plugs? They were the only BOSCH plugs the store had, I actually did ask for the copper plus but they didn't have any.

Been there done that. They are a marketing gimmick. Use the factory recommended parts, fluids and then have fun.

Well, they were only $2 each and they work. Can some say with some certainty that these plugs are going to cause some damage?

Do what you wish. It's your car. I had bad luck with them. They ran good for about 1500 miles and then started to miss. I took them out and all were fouled. Never again...

Douge · #15 03-11-2009, 01:44 PM

Just wanted to update that my local mechanic concurred with you guys and said the platinums would foul prematurely and that he felt the car would run better on the coppers so they are coming out.
