[Bettez88]

Doe anyone know the correct torque spec for the 16 spark plugs in my 2003 Mercedes SL500?

I can take a look in DAS/XENTRY tomorrow.

I believe it's 28Nm. It's a 230, right?

See spark plug section towards the bottom.

Gudentight?

Ford 2 valve 4.6 motors were really critical to get the right torque. I would do 20# with a little antiseize. No problems w/spitting plugs so I would take an educated guess at the same for your Benz.
