Hey guys, I have heard alot of people running these, my question is where can I purchase one and does it plug into the PCM or does it thread into the block or cylinder head somewhere. The car is a 97 z-28 by the way. Thanks in advance.

 

It plugs into the computer.

 

Do you know by chance where I can purchase one at?

 

dealer for about $35. Take the little plate off of the pcm and pop it in there.

 

call up one of these guys........better prices than just going to the dealer.

The LT4 knock module helps to eliminate false knock caused by RR's or headers. Are your getting knock?
