Instructional: Installing Spark Plug Wires Set on a 430CLK.
Spark Plug Wires Set: Bosch OEM# W0133-1829574 Other part# 09850
rockauto.com BOSCH Part # 09850 is $167.89 + $11.31 Ship = $179.20
The engine has sixteen spark plug wires, which fire sequentially,
and the plug wires must be installed in a specific order.
First Image:
The guide to installing each wire is "lettered" right on the heads, near each cylinder's plug ports.
Second Image:
There are 4 different wire types which are marked on the metal wire boot: G, K H and L.
The wire set has:
9 of 0 356 912 948, they are marked "G" (9 5/8")
4 of 0 356 912 950, they are marked "K" (10 3/8")
2 of 0 356 912 952, they are marked "H" (11 3/8")
1 of 0 356 912 954, it is marked "L" (12 1/4").
Third Image:
Each coil has two ports which are marked on the face of the coil.
The upper port is "a", and the lower port is "b".
Fourth Image:
Text version of the Head Markings.
The installation is straight forward. Use the head markings to install each plug by matching
each plug port, to the correct wire type, to the correct coil port.

Many will tell you the plug wires will last the life of the car if not abused (IE removed properly when changing the plugs). Personally, I'm pretty sure everything has a useful lifespan. I'm changing mine with the next plug change. 11 years and close to 200K miles - I'm pretty sure I'm due.
