Denso Heated Oxygen Sensor

Experience unparalleled engine performance with the Denso 234-4209 Universal Heated Oxygen Sensor. This 4-wire sensor is engineered to meet rigorous OE standards, ensuring precise oxygen measurement for enhanced fuel efficiency and optimal engine function. Its universal fit and threaded mounting type allow for straightforward installation across a wide variety of vehicles. The sensor features an innovative aluminum oxide trap layer that protects the ceramic element from silicone and lead poisoning, safeguarding the platinum electrode and extending the sensor's lifespan. A double protection cover helps maintain proper unit temperature for quicker response times and further protects the ceramic element from contamination. The stainless steel housing provides corrosion resistance, while a porous PTFE filter allows atmospheric oxygen to enter without permitting water or contaminants to seep into the casing. Denso universal oxygen sensors arrive without a connector, requiring you to reuse the old connector for seamless integration. This sensor is compatible with a vast array of makes and models, including Acura, Chevrolet, Dodge, Honda, Lexus, Mitsubishi, Toyota, and many more, spanning from the late 1980s through the mid-2010s.
