Oxygen Sensor Upstream for Toyota Camry, Lexus ES350 RX350 RX450H
This upstream oxygen sensor from IWOKPHD is engineered as a precise, direct-fit replacement for select Toyota and Lexus models. By monitoring exhaust oxygen levels before the catalytic converter, it helps the engine maintain optimal air-fuel ratios, delivering smoother acceleration, steadier idle, and better fuel efficiency while reducing emissions. The heating-type design warms the sensor quickly for accurate readings, which improves cold-start performance and reduces overall engine check-light occurrences. Compatible with a range of popular models including Toyota Camry and Lexus ES350, RX350, and RX450H, this sensor is built to withstand the engine bay’s heat and vibration for long-lasting performance.
All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
