| Product DescriptionThe knock sensor is one of the most important sensors in your engine. Your knock sensor reads how much knock is going on in the engine. If you have a faulty knock sensor, you are playing Russian roulette with your motor.
 This is the same knock sensor that Mitsubishi put on your EVO from the factory.
