Purchase precautions
1. Please purchase according to the original OE and OEM numbers of the vehicle. If you are unable to confirm the specific model, please contact us promptly and we will provide guidance within 24 hours. You can also provide the following information about the vehicle in a timely manner (frame number, model year, displacement, engine code, fuel type) so that we can accurately match the appropriate oxygen sensor for you. Do not purchase directly without confirming the suitability of the model, as incorrect parts may result in inability to install and use.
2. Before installation, please ensure that the engine is cooled down to avoid high temperature burns. When installing, please tighten the interface to prevent air leakage.
3. After product installation, if there are problems such as faulty lights or abnormal signals, please contact us in a timely manner. We will reply within 24 hours and help you troubleshoot and solve the problem.
4. This product is for exclusive use by vehicles. Please do not modify i

WJIECO Core advantages of the product
1. Precise monitoring and stable output: Using high-precision sensing chips, it quickly responds to the oxygen concentration in the exhaust, provides real-time feedback data to the ECU, accurately adjusts the air-fuel ratio, avoids the mixture being too rich or too lean, improves combustion efficiency, reduces carbon deposition, and extends engine service life.
2. Factory adaptation, easy installation: Strictly follow the original car specifications for mold production, with interfaces and dimensions perfectly matched with the original car, without modification or debugging. DIY can be easily installed, saving time and effort
3. High temperature and corrosion resistance, durable: The shell is made of high-strength high-temperature alloy, which can withstand the high temperature environment of the exhaust system (up to 900 ℃). It is resistant to corrosion, aging, and exhaust gas erosion. Its service life is far beyond the industry average, reducing the replacement frequency.
4. Energy conservation and emission reduction, compliance and standards: Optimize fuel combustion efficiency, effectively reduce fuel consumption, reduce harmful gas emissions such as carbon monoxide and hydrocarbons, easily pass annual inspections, and respond to environmental policies.
5. Stable compatibility and fault prevention: Equipped with high-quality ceramic chips and waterproof seals, it is waterproof and dustproof, avoiding sensor failure caused by moisture and dust; Stable signal transmission, eliminating problems such as engine shaking, unstable idle, and constant malfunction lights caused by oxygen sensor failures.
