Oxygen Lambda Sensor Filter Adapter, 2-Piece Extensions, 46.5mm Oxygen Lambda Sensor, Lambda Probe Extension, Automotive Oxygen Sensor Extension Adapter for Engine Exhaust Systems M18 x 1.5

High-strength and durable material: The oxygen sensor filter adapter is made of high-quality stainless steel, resistant to high temperatures up to 850°C. It is waterproof, rustproof, and corrosion-resistant, with a solid structure and strong seal, ensuring stable long-term use and high sealing performance.

Universal fit design: The lambda extensions fit the M18 × 1.5 mm threaded interface, compatible with the oxygen sensor installation requirements of most models. No cutting or drilling is required; it directly replaces the original parts and lowers the modification threshold.

Built-in filtration function: The oxygen lambda sensor has a built-in microfilter and catalyst to effectively intercept impurities and optimize exhaust data return, reducing false alarm error codes of the sensor and improve the accuracy of system operation.

Fuel efficiency optimization and upgrade: The lambda sensor extension improves the air-fuel ratio calculation by extending the distance between the oxygen sensor and the exhaust system, reduces fuel consumption, improves combustion efficiency, and contributes to emissions control compliance.

Multi-scenario adaptability: The automotive oxygen sensor extension adapter is suitable for HHO systems, automotive exhaust optimization, and the installation of upstream and downstream O2 sensors. It offers a two-part configuration that accommodates modification and maintenance needs, including after-sales technical support.
