The NGK C542 38-65 ignition knock sensor, manufactured by NGK Spark Plug Co. Ltd., is a crucial component in the ignition system of your 2021 Lexus ES250 with a 2.5L L4 engine. This sensor is specifically designed and engineered to detect and measure ignition knock or detonation, which is an abnormal combustion phenomenon that can lead to engine damage if left unchecked.
