This is a brand new replacement Knock sensor for your Honda/Acura vehicle. Direct replacement for factory part numbers:
30530-P2M-A01 & 30530-PV1-A01
Factory knock sensors have a limited life span and over time build up resistance which in turn give intermittent false signals to the ECU. Why buy a used Knock sensor with an unknown amount of use left in it? Why buy an OEM sensor that will cost you an arm and a leg and not provide you with the warranty we are offering?
If you purchase a New Knock sensor from us you will receive a Lifetime warranty.
