Mercedes-Benz W210 E-Class Spark Plug Replacement

One basic tune-up procedure for just about any car on the road is the replacement of your spark plugs and spark plug wires. I recommend examining your spark plugs every 30,000 miles and as the car ages, it'd be a good idea to check them more frequently. If you see signs of burnt electrodes, oil, etc., replace them. In reality, you can probably go longer than that, (most manufacturers recommend an interval of 100,000 miles) but, you never really quite know how long the plugs are going to last. A lot of factors can contribute to the plugs wearing out faster than you might expect.
On the M104 engine, Mercedes has eliminated the use of a distributor by integrating a "wasted spark" ignition setup with three coils. In a wasted spark system, the spark plugs fire in pairs even though one plug is on the compression stroke and the other plug is on its exhaust stroke. The extra spark on the exhaust stroke has no effect and is considered to be "wasted." The main advantage of using this setup is that there are half as many components needed for the engine and thus less expensive to produce.

The L6 M104 motor was only in the w210 the first MY or 2. I. This vid provides little info that would help owners m112 v6 or m113 v8 powered w210s
