What is the socket size needed to remove the bolt holding the knock sensor in place? This is the only thing preventing me from replacing it as I speak. I want to make sure I buy the right one. I have a 18" 3/8 extension plenty long for the job.

 

If i remember correctly it's a 12mm. I'm almost positive...

 

What does that translate in inches? I don't think mm are used in the US, correct?

 

you can get metric units...

 

i have alwasy had a standard and metric set on hand. They dont' always fit well enough to use a standard socket on a metric bolt.

 

12mm and a burnt hand on the intake

 

12mm swivel socket and small **** hands

 

i used a 12mm 1/4" drive socket, swivel, and long extension...and used a 3/8"-1/4" adapter and hooked it up to my 3/8" ratchet for more leverage. The only hard problem was getting the socket to sit flush on the bolt because i couldn't see the bolt.
