Spark Plug Wires for 450SL
I'm a first time poster. I recently acquired a 1976 450SL (my dream car)- the second MB we own. I am doing an overall tune up and I am wondering about the spark plug wires. I changed the plugs and noticed each plug has a rather large metal connector that goes around the plug. Also, the old plugs had the little screw on top removed. My questions are, in replacing the plug wires, do I really need to get ones with these metal boots, or would regular plug wires work. Also, if I replace with the metal booted kind, do I leave the metal screw on the top of each spark plug on, or remove them before I attach the metal boot. Thanks you any assistance you can give. Also, kudos to Phil who has helped me with a lot of parts.
