• ✅ MAXIMIZES FUEL ECONOMY & LOWERS EMISSIONS - O2 sensor is an essential tool for fuel efficiency and reduction of CO2 emissions and it measures the air to fuel ratio entering car's engine and helps determine if your car is starting and running smoothly. It also monitors the emissions from car’s exhaust and measures the amount of unburnt oxygen. The engine's computer uses the measurements to adjust the ratio to an optimum value of 14.7:8 and increase in your fuel savings.
• ✅ SUPERIOR & CONSISTENT PERFORMANCE - Designed by skilled artisans who have a trained eye on every detail, every single Ewandor sensor passes quality inspection and testing before packaging to ensure a long service life. Please be noted that perfect functioning of oxygen sensors can be jeopardized by many factors: environmental influences, such as salt and dirt, large temperature fluctuations, poor-quality fuel, and soot and oil residues in the exhaust gas.
• ✅ TIPS ON MAINTENANCE - The signs of a bad oxygen sensor include that the check engine light constantly comes on and you experience poor gas mileage since the fuel delivery and combustion system aren't working at the optimal level. In addition, excess fuel may be injected into your engine system, and it will produce a foul, rotten-egg smell. Waiting any longer will reduce your sensor's ability to capture accurate voltage signals.
