For my 92 Z28 5.7 TPI, and friend looked up the knock sensor for me and told me that there is two knock sensor for the 5.7's so the computer said go to match up with OEM, so in my case I will need the correct one, unless I buy both of if and return the one I don't need.

And what to you torque the knock sensor to?

 

Well I did a search and found this #10456549. Is this the correct part number?

 

Nobody know the torque down spec is?


Or its hand tighten?

 

Ok I got 13lbs from the dealer and 14lbs from a friend? So with one is the correct one? Thanks..

 

10456549 is correct. Torque isn't that critical. It's tappered pipe thread, just make sure the threads have sealant on them & snug it in there. 15 ft lbs. no more.

 

According to the AC-Delco website

92' Z28 350TPI

Sensor, Knock
#213-92 AC-Delco or
#10456549 GM Corp

So yes that is the right #. As for the torque specs follow gm manual.


edit: looks like someone beat me 2 it

 

Thanks guys! I will try 14-15f ft/lbs of torque.
