AC DELCO 213-3521 [KNOCK (DETONATION) SENSOR]

This AC DELCO knock or detonation sensor is a new part. It is the same piece that you would receive if you purchased it from your local GM dealer.

A knock sensor is like a very small electric microphone that is placed on the engine. It listens for pre ignition knocks and then sends a signal to the ECM. The ECM then will make adjustments to the engines timing. If the knock sensor fails, it possibly can cause serious engine damage as continuous pre ignition can cause a fracture in the pistons!

This knock sensor features the following specifications:

  • Brand New AC Delco part
  • Replaces dealer part number: 12589867, 213-3521
  • Built to strict quality control standards
  • Direct replacement
  • 100% factory tested
  • Mounts in either the engine block, cylinder head, or intake manifold
  • (1) Wire Style

These are electrical parts and are all tested before they leave our manufacturer. This electrical item is not returnable; it is only eligible for exchange

1 Year Warranty
