Renix Knock Sensor Adapter

Included with new orders for products below, this adapter enables the engine bracket to use the same thread boss occupied by the Knock Sensor. This handy adapter holds the engine bracket in place, moving the sensor outside the bracket. Order only if adapter is missing when installing a used left Super Bracket on a 1987-1990 4.0L Jeep Cherokee XJ or Comanche MJ using the original RENIX fuel system. THIS IS NOT THE SENSOR, JUST AN ADAPTER.  If you are looking for the sensor, it is available on Amazon (Standard Brand Part Number KS99).
