Spark Plug Torque specs?
I'm replacing the spark plugs on my 2007 SL550 today and was hoping to verify the torque specs. I believe I read 18lbs but can someone verify please? I don't have access to a repair manual at the moment.

Thanks!!

15lbs is the loosest, and 20 lbs is the tightest, so 18lbs is just fine right in the middle.
