Ok i went to order a LT4KM from GMpartdirect.com It has a spot to place the part #, so i typed in ( 16214681 ) This # was given to me from 2 individuals on the board. However when the part comes up, it's description states, "Knock Sensor".

Can someone look at the picture and tell me if this is the Knock Sensor that goes into the block, or the Knock Module from an LT4 that I need for my header install? I dont want to order it and have it be the wrong part ...

I double checked the part # just to be sure, and thats what both ppl have told me, and that is exactly what i typed in. Any help would be appriciated. I want to get my headers in and over with asap.

 

That's definetly a knock MODULE

 

lol ok. Gotta love GM's part market manager huh ...
