According to one post I read, but can't find now (with excellent instructions) it specifies 17.4 ft./lb. or 24 n-M. I was informed by an experienced mechanic that you should go a bit lower to start with since knock sensors are fairly sensitive to over-tightening and may render useless if stressed too hard. Say 3-4 ft./lb. less to start with.
This post recommends 16 ft./lbs.

Good luck
that the knock sensor does
the knock sensor in on the drivers side of the block toward the rear, and it's under the intake manifold.
on top of the engine under the air box
It is located on the engine block drivers side.
You can find the knock sensor on the top side of the engine under the intake manifold. It is easiest to find from the driver's side and is at the back of the engine block.
The torque specification for the knock sensor on a 1997 Subaru Legacy is typically around 8.5 ft-lbs (or 10 Nm). It's important to ensure that the sensor is tightened to the appropriate torque to avoid damage to the sensor or the engine block. Always refer to the vehicle's service manual for the most accurate and specific information.
Where is the knock sensor located on a 1999 Subaru Forester?
That depends entirely on what happened to it to make it need repairing.
On a 1999 Subaru Legacy Outback, the knock sensor is typically located on the engine block, near the intake manifold. It is usually found on the driver's side, towards the back of the engine, and can be accessed by removing some components for better visibility. The sensor is a small, cylindrical device screwed into the engine, designed to detect engine vibrations and adjust timing accordingly.
If somebody knocks on the front door of the Subaru, the KNOCK sensor, sets off the KNOCK Alarm....LOL
on top of the engine block under the intake manifold. it can be accessed without removing the manifold. easy fix!
The knock sensor is located near the idle air control solenoid valve on a 2001 Subaru Forester. The knock sensor is responsible for sensing vibrations caused by engine knock.
