Description

The Denso 234-4791 OE Identical Oxygen Sensor is designed to meet or exceed original equipment specifications, ensuring optimal performance and compatibility. Its construction includes an aluminum-oxide trap layer, which shields the ceramic element from silicone and lead poisoning, thereby preventing damage to the platinum electrode. A double protection cover is incorporated to maintain the sensor's proper operating temperature, facilitating quicker response times and protecting the ceramic element from contamination. Featuring a rugged, watertight stainless steel housing, this sensor effectively resists corrosion and contamination. The inclusion of a porous PTFE filter allows atmospheric oxygen to enter the sensor freely while simultaneously preventing water and engine contaminants from entering the casing. The sensor is heated and utilizes a Planar sensor type, with four wires and OE Type connectors for straightforward installation. It has a threaded mounting type and a zirconia material composition. With a thread diameter of .708" and a wire length of 648mm (25.5"), the Denso 234-4791 is compatible with a wide range of Jaguar and Land Rover vehicles from 2015 to 2024. This includes various trims such as the F-Type, Range Rover Sport, XJ, and XE models. The sensor comes with a 12-month warranty.
