Knock sensor replacement

It forces this to be pig rich to avoid any detonation and further damage.
Knock sensor is not something to go to the parts store for, and not something to get from a junkyard car or not to be bought used. they almost 100% have a failure rate after being 5 years old, the plastic casing gets brittle, and hard, and develops small cracks, that is when they fail.
Get new, from Subaru. should be between 45 and 75 bucks depending on year and model.

It takes a wobbler on the end of a 3/8" drive to get to the awkward bolt that hold it in place on the block. It is a pretty ez job to do yourself, but it takes some patience to swap out. Just don't tighten new unit very tight, or you will break the plastic collar around the fastening bolt.

Don't go aftermarket on this.
