As a heated sensor, it quickly reaches operating temperature to provide accurate oxygen level readings, which are critical for the engine control unit to adjust fuel mixture efficiently. The sensor’s 5-wire design and 20 gauge wiring ensure consistent electrical performance, while the 48.74-inch wiring harness length allows for convenient routing within the engine bay. The threaded mounting type with an 18.0 mm diameter thread provides a secure and precise fit, minimizing the risk of leaks or sensor movement. The radiused polygon male connector is designed for a reliable and stable electrical connection, reducing the chance of disconnection or corrosion over time.\u003c\/p\u003e\u003ch2\u003eWalker Products Aftermarket Line\u003c\/h2\u003e\u003cp\u003eThis oxygen sensor is part of the Walker Products Aftermarket line, which focuses on providing replacement emission control components that meet or exceed OEM specifications.
