Yes it can be damaged by over tightening it. It should be no more than 15 ftlbs as I remember it. It also had to be in the correct orientation as well.
Are you sure it's not real knock? |

I read on I think Autospeed that a good listening device is better for tuners than relying on the stock knock sensor if you want to be real sure of knock threshold.

I have not checked to reference other models but the 06 wrx is 17.4 ft/lbs to be exact. Here is the page from the service manual, make note of the orientation of the sensor as well.

Hehe. Installing the knock sensor in the wrong direction--I found to be a bit difficult due to the confined space and relatively short wire connections.

Since the last one was overtorqued, I would replace it regardless of any other factor. It's sensitive equipment that needs to be installed properly to function properly. Who knows what could be wrong inside????
As far as knock is concerned, run higher octane fuel, that should help greatly with your knock problems. Just don't put any lead additives. |
