Subaru OEM Knock Sensor WRX 2008-2014 / STI 2008-2021 | 22060AA140

This genuine Subaru OEM knock sensor is a critical engine management component designed to detect pre-ignition or detonation within the combustion chamber. Engineered for precise vibration monitoring, it sends real-time data to the ECU to adjust ignition timing, preventing potential engine damage. A faulty sensor often triggers a check engine light and can result in decreased fuel efficiency or audible engine pinging. This factory replacement ensures optimal signal accuracy and long-term reliability for EJ-series engines. It is a direct-fit component specifically calibrated for the 2008-2014 WRX and 2008-2021 STI models. Maintaining a functional knock sensor is essential for preserving engine longevity and performance under high-load conditions. For maximum performance and safety, pair this hardware with a specific custom Migtuned etune to optimize timing maps for your vehicle's specific year and model.
