Product Description
The high-quality oxygen sensor specifically for your vehicle
This DENSO oxygen sensor is manufactured and tested in strict accordance with OEM standards. It can precisely monitor the oxygen content in exhaust gas, optimize the air-fuel ratio, improve engine efficiency, and reduce fuel consumption and harmful emissions. It can be directly replaced for your old or faulty sensor without any modification!
Main features and advantages
• Robot laser welding: Ensures seamless installation, no air leakage, and stable signal transmission.
• Multiple protections: Multi-pore polytetrafluoroethylene filter + double protective cover can block water, oil and impurities, protecting the ceramic components and platinum electrodes from silicon/zinc poisoning.
• Durable stainless steel housing: Corrosion-resistant, waterproof and heat-resistant, suitable for harsh working environments.
• Fast response: Maintains the optimal working temperature, quickly transmits data to the ECU, solving problems such as unstable idle and insufficient power.
Important compatibility instructions
1. Before purchasing, please check your vehicle's vehicle identification number (VIN), year, brand, model, engine displacement and transmission type. Vehicles of the same year model may have different sensor specifications due to different emission standards (California/Non-California).
2. If you are unsure about compatibility, please send us a message and attach your vehicle information. We will help you confirm quickly!
