SL/R129: Spark Plug Question


What is the best plug to install in these guys? My BMW's use NGK's vs. Bosch, way better, but I don't know what to use here.

Help would be appreciated.

Thanks
This is a platinum electrode resistor plug which is no longer in production and has been replaced by the Bosch FR8DPP33+ (stock # 7422), a double platinum plug. The MB part number is A 003 159 94 03.
You can get them from Autohaus AZ for $5.18 each.
The F8DC4 is a conventional non-resistor chrome-nickel alloy plug used in the earlier M119 engine...

Thanks, I knew what the book said, but also found out there weren't any around. Figured I'd ask and maybe someone would either know the superseded part number, or knew a better plug to use.
Thanks again,
Mike

My Mercedes Benz SL500 has 8 cylinders and uses 16 plugs.
Yeah buddy, it's a party

In my house we need a total of 54 spark plugs (Groan). Oops, forgot the weed eater, snow blower and lawn mower, so 57.

Thank you gentlemen
