Improve Fuel Economy: Marsflex oxygen sensor helps optimize fuel efficiency by providing accurate real-time data to your engine's ECU, ensuring the ideal air-fuel ratio (14.7:1). Over time, old sensors degrade, causing incorrect fuel mixtures (too rich or too lean). Replacing them with a high-precision Marsflex sensor restores proper combustion, potentially improving fuel economy by 5-15% while reducing emissions. For best performance, we recommend replacement every 60,000–80,000 km
