Another Spark Plug Question
My 2003 ML350 is ready for new spark plugs. The manual suggested Bosch
FR8DPP33 plugs. I ordered the plugs from an online parts house. When my order arrived, they shipped Bosch 7422 indicating the former plugs were superseded by the 7422 plugs.
Is it OK to use the 7422. I was concerned because the gap is wider on this plug.
