RB25 knock sensor socket size and torque?

[KlanjacOFF]

Wanted to see if anyone knew off the top of their head what size socket to use for the RB25 knock sensor, definitely needs to be a deep one. Also need to know what to torque it down to as apparently that is pretty important for reading knock correctly. FSM says 16-21 Nm for the RB26, but it looks like a different style knock sensor.

meh turn till tight. it doesnt have a precision torque requirement like flywheel bolts, crank pulley bolt, or internal parts.
