129X also in my 300SD. Hell, it also fit my 560 with a simple reclock.

The idle output is a bit lame on my SD with the one from Eagle, as soon as engine RPM goes up 250-400rpm output increases big time. Not sure why, perhaps the pulley reduction is different than the V8. The one on the V8 is from Autozone.
