• NTK part number 25694 for application matching

Application Details

Fits 2007-2009 Land Rover LR3, downstream right and downstream left, with North American Specification and OE equivalent design notes. Fits 2007-2009 Land Rover Range Rover Sport, downstream right and downstream left, with North American Specification and OE equivalent design notes. This part cross-references Bosch (e.g., 13476, 15055) for the same application.

What It Helps Address

• Faulty oxygen sensor readings
• Check engine light concerns related to the sensor circuit
• Slow sensor response from a worn heated element
• Incorrect air-fuel feedback affecting emissions control

Installation Notes

Use the threaded mounting style and harness length to confirm the replacement matches the original sensor layout before installation. Verify the connector routing and downstream position requirements for the vehicle application. Confirm part number 25694 against the original sensor before ordering.
