Torque spec for tightening the spark plug

Hi,

I have E85 2006 Z4 3.0i.
What is the torque spec for tightening the spark plug?
I used 17ft.lbs, and used NGK spark plugs from O'Reillys,
but the Service Engine Soon light doesn't go away.
(I made sure it is not the ignition coil as I swapped it with another cylinder)
My suspicion is the spark plug itself or I didn't tighten it correctly.

Torque spec & any other suggestion welcome!

My notes confirm 17ft.lbs.
Have you scanned the OBD?
What makes you think it's spark plug related?
