During operation, spark plugs are subjected to wear and fouling, so they should be replaced during intervals to ensure optimum engine performance. Worn or corroded spark plugs are no longer capable of igniting the fuel properly and can cut down on your fuel economy. An increasing number of automotive manufacturers install Bosch spark plugs in their vehicles. Bosch OE Specialty Spark Plugs feature the same fit, form, and function as the OE spark plugs currently installed on your vehicle. They ensure optimal performance and a long-lasting spark plug life at a price tag that will suit your pocketbook.

I bought this kit over a year ago now, and I'm really happy with it. It's a complete overhaul of the ignition system, save for the coil (which I also bought here, and which I'm also happy with).The ONLY thing wrong with this kit is the park plugs. For the 560SEL and many other models, Mercedes specifies resistor-less spark plugs. The Bosch 7911 (WR9DC+) spark plugs in this kit do have resistors, however.I spent under $20 on eight alternative spark plugs that do not have resistors, and have been running those with the rest of the components in this kit. For the value and ease of just buying this kit in order to get all of the ignition system parts in one fell swoop, it's worth it despite the spark plugs.
