NGK Toyota 4Runner 2004-2003 Direct Fit Oxygen Sensor

NGK is known worldwide as a top supplier of original equipment oxygen sensors, and this direct-fit sensor is built with that same expertise. If your check engine light is on, or you're noticing less-than-ideal fuel economy, a faulty oxygen sensor could be the culprit. This part plays a crucial role in your vehicle's onboard diagnostic system, constantly feeding information back to the engine control unit to manage the air-fuel ratio, which helps maximize fuel efficiency and reduce emissions.

At its core, NGK is a ceramics company, and they use advanced technology to control the ceramic element in their oxygen sensors from start to finish. This particular sensor features an advanced ceramic element with a three-stage plasma jet and deposit trap overcoat. This design helps protect the element from contaminants that can cause poisoning, ensuring reliable performance and resistance to failure. It's designed to fit a range of vehicles, including models like the Toyota 4Runner, Toyota Camry, and Lexus ES350.
