Breaker Bar
1/4 inch rachet
1/4 inch extension (I got 14")
1/4 inch 12mm swivel socket
Needle Nose Pliars
Knife (to cut the ziptie)
Telescoping Magnet


Go out and get these tools before doing the knock sensor install. Save yourself the time and blood. I found the proceedure here:

Don't bother using a conventional socket or wrench. Get the extension and swivel head!!! That is all. I'm done, no blood. Took 20 minutes. Most of the time was trying to get the knock sensor wire connectors off. =)

 

All I used was a swivel, dikes, and my girlfriends small arms. 10 minutes and she got 3 times more dirty than I did.... That was awesome....

 

Lucky guy, you better marry that girl.
