lt4 oem knock module
I have one sitting as a spare, curious why the demand for these (they are obviously out of production), just seems inflated.
Seen some websites list as LT4 KM but with LT1 KM part number people need to double check before buying.
So most of us who do run RR got the LT4 KM. Back then it was a $27 part at dealership
Now that many LT1/4 parts are extinct….supply & demand dictates what they can sell for
The GM part # for the LT4 module is 16214681
The PCM can be tuned to lower knock perception....not the ideal way to deal with it though
