1980 450SL - Recommended Spark Plugs and Wires

[supercanuck]

Hey all,

I am about to change out the spark plugs and wires on my 1980 450SL. I am going to go with the Bosch wires, but I don't know anything about the different types of spark plugs. Can anyone recommend any specific spark plugs, or do they all perform more or less the same?

Thanks!
Zack

If you have an owner's manual, it lists all the recommended replacement parts / fluids with specs for a routine tune up.

Just curious, why no platinums on these? I have had the best life out of a platinum plug on 95% of my other vehicles.
