Standard Ignition Ignition Knock (Detonation) Sensor P/N:KS147
Standard Motor Products
Standard Ignition KS517 sensor for the 2017-2018 Subaru Forester H4 2.5L listens for engine knock vibration and sends a signal to the engine computer.
A lit check engine light or pinging under load can mean the knock sensor is worn, though the sensor's wiring harness or the engine computer can be behind those signs too, so find the cause before replacing the sensor.
This listing is one knock sensor for the 2017-2018 Subaru Forester H4 2.5L, and that engine takes one.
