![Question](https://mbworld.org/forums/images/icons/icon5.gif)
Pulled a plug on my '02 R129 M113. They look like they have never been changed. Ugh!![Mad](https://mbworld.org/forums/images/smilies/mad.gif)
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.![nix](https://mbworld.org/forums/images/smilies/nixweiss.gif)
Help would be appreciated.![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)
Thanks

Per the owner's manual (click here) the 2002 M113 engine use Bosch F8DPER plugs.
This is a platinum electrode resistor plug which is no longer in production and has been replaced by the Bosch FR8DPP33+ (stock # 7422), a double platinum plug.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...

cliffy;
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 Figured I'd ask and maybe someone would either know the superseded part number, or knew a better plug to use.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

It's funny, my BMW 850 has 12 cylinders and uses 12 plugs.
My Mercedes Benz SL500 has 8 cylinders and uses 16 plugs.
Yeah buddy, it's a party![Cheers](https://mbworld.org/forums/images/smilies/cheers.gif)
In my house we need a total of 54 spark plugs (Groan). Oops, forgot the weed eater, snow blower and lawn mower, so 57.![EEK!](https://mbworld.org/forums/images/smilies/eek.gif)
Thank you gentlemen
