Heated Oxygen Sensor, 0.708" Thread, 12.99" Harness

The Denso DEN-234-4659 is a direct-fit, downstream oxygen sensor engineered to meet the strict OE standards for unparalleled performance. Each component is precision-built for an exact replacement and a first-time fit, ensuring optimal engine function. This sensor incorporates Denso's exclusive aluminum oxide trap layer, which safeguards the ceramic element from silicone and lead poisoning. This protection is crucial for maintaining the integrity of the platinum electrode, leading to improved engine performance, greater fuel efficiency, and extended longevity. The double protection cover also helps maintain proper unit temperature for quicker response times, critical for fuel economy. The watertight body and the PTFE filter allow atmospheric oxygen to enter while preventing water and contaminants from compromising the sensor's internal components. The sensor type is heated, has a 4-wire configuration, and features a threaded mounting with a 0.708-inch diameter. The wiring harness is 12.99 inches long, and it utilizes an OE-type connector for seamless integration. This Denso oxygen sensor comes with a 1-year warranty.
