e320 coil wire change
 

Hey guys, the weather improved..so tomorrow I will change the plugs and the resistor ends which have been causing me so much trouble.
Can someone please list the type of tools I need?
The sears metric tools that I wanted to buy in a set are sold out locally but I need the following:

Spark plug tool
hex key to remove the cover..type?
anything else?
thanks.

Put a light coat of neversieze compound on the plug threads to make spark plug removal easier next time. And put a light coat of silicone (dielectric grease) on the inside of the boots so they won't stick to the porcelain of the plug and will seal out moisture.

<<hex key to remove the cover..type?>>
