Walker 250-241258 Oxygen Sensor - Downstream Right

OE Oxygen Sensor for Porsche Cayenne

Walker Products OE oxygen sensor Part Number 250-241258 is an OE-style replacement built for specific vehicle application and sensor position. It is designed for the downstream right location on select Porsche Cayenne models, helping the ECU receive the feedback it expects from the exhaust system.

For Porsche Cayenne owners diagnosing a check engine light, poor fuel economy, or elevated emissions, this downstream oxygen sensor provides a direct-fit service part for the right-side exhaust position. Walker Products OE focuses on application-specific fitment, making 250-241258 a practical choice for restoring sensor function on the correct bank and position.
