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, waterproof, rustproof, and corrosion-resistant, with a solid structure and strong seal, ensuring stable long-term use and high sealing performance.

Universal fit design: 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 feedback, reducing false alarm error codes from the sensor and improving system operating accuracy.

Fuel efficiency optimization and upgrade: Lambda probe extension Improves 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, offering a two-part configuration that adapts to modification and maintenance needs.
