【Easy to Use】The lambda sensor socket is easy to use. Simply insert the oxygen sensor and turn it to remove it easily. The side opening of 8.8 mm/0.35 inches can be easily passed through the cables to avoid damage to the wiring harness. The oxygen sensor socket is suitable for most wrenches available on the market and provides extra leverage even in tight areas, making it easy to use.
【Compact Size】: The side wire cutout oxygen sensor socket features a dual interface design and is equipped with a 1/2 inch (12.5 mm) square screwdriver and a 7/8 inch (22 mm) hex socket. The overall dimensions are 91 x 31 mm. The side cut-out makes it easy to remove the oxygen sensor when connecting the harness, preventing damage to the cable.
Wide applicability: this sensor socket wrench is suitable for removing and installing oxygen sensors in most vehicle models and is compatible with both heated and unheated sensors found in most vehicles. It is an ideal tool for replacing, cleaning and testing oxygen sensors in motor vehicles. The oxygen sensor socket conveniently stores in toolboxes in the garage, door armrest compartments, or storage compartments in the center console without taking up much space.
Robust construction: the 22 mm lambda sensor key is made of high-strength chrome vanadium steel and has undergone a high-hardening process. It is characterised by excellent rust resistance, wear resistance and high torque and does not deform easily even under harsh working conditions and does not break. Thanks to the blackened surface treatment, the lambda sensor tool is resistant to oil stains, does not slip off easily during operation, is stable and durable in use.
Highly efficient protection: the oxygen sensor socket has been specially developed for the safe and convenient installation and disassembly of oxygen sensors in motor vehicles. It effectively protects the oxygen sensor from damage and improves maintenance efficiency. The sensor socket wrench helps maintain good oxygen concentration and good air-fuel ratio of the oxygen sensor, ensuring long-term smooth operation of the engine.
