2000 E320 Wagon 4matic, 141,000 miles, V6 with 2 plugs per cylinder:

Ready to change my spark plugs, had a couple of missfire codes.

I pulled one plug, it is a Bosch Platin R1 971. Have not found it in the auto part chain stores.

What are my other choices? Bosch or NGK? Part number? Where to buy, dealer wants $15 per plug.

At this mileage should I consider changing the plug wires too?


Thank you, Patrick
