About LABWORK 4
What is LABWORK 4?
LABWORK 4 is a premium replacement oxygen (O2) sensor designed specifically for 2004–2008 Nissan vehicles equipped with the 3.5L V6 engine, including the Altima, Maxima, Murano, and Quest. This sensor monitors oxygen levels in the exhaust stream and sends real-time data to the engine control unit (ECU) to optimize the air-fuel mixture. A failing O2 sensor can trigger the check engine light, reduce fuel economy, increase harmful emissions, or lead to premature catalytic converter failure. LABWORK 4 delivers a reliable, factory-spec solution to restore engine performance, improve fuel efficiency, and help pass emissions testing with confidence.
