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 robust 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 reduces 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 sensor alarm error codes and improving system operating accuracy. Fuel efficiency optimization and upgrade: The lambda sensor extension improves air-fuel ratio calculation by extending the distance between the oxygen sensor and the exhaust system, reducing fuel consumption, improving combustion efficiency, and contributing 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. Its two-part configuration accommodates modification and maintenance needs.
