This allows for control near the stoichiometric air-fuel ratio, which most effectively purifies harmful substances in exhaust gases. Thus, NTK O2 sensors are important components for reducing harmful substances in exhaust gases.\u003c\/p\u003e\n\n\u003cp\u003eSpecifications\n\u003cbr\u003e【Features and Structure】\n\u003cbr\u003eZirconia elements have the characteristic of generating electromotive force due to differences in oxygen concentration at temperatures exceeding 300°C. Utilizing this characteristic, zirconia-type sensors detect the difference in oxygen concentration between the inside and outside of the element (atmosphere and exhaust gas) and feed back to the ECU whether the fuel mixture is rich or lean relative to the stoichiometric air-fuel ratio.\n\u003cbr\u003eWide-range air-fuel ratio sensors can detect how rich or lean the mixture is relative to the stoichiometric air-fuel ratio. Therefore, more precise engine control than with zirconia O2 sensors is possible. It also allows for engine control outside the stoichiometric air-fuel ratio (λ=1), such as lean-burn control. Furthermore, there are early activation wide-range air-fuel ratio sensors that maintain the characteristics of conventional wide-range air-fuel ratio sensors while improving heat resistance and durability, and achieve early activation (starts operating within 5 seconds of turning the engine key ON) through an integrated structure of the element and heater.\n\u003cbr\u003e【Necessity of Replacement】\n\u003cbr\u003eO2 sensors are constantly exposed to exhaust gases exceeding 600°C and accumulate combustion products, working in a very harsh environment.\n\u003cbr\u003eUsing a deteriorated or damaged O2 sensor can lead to various problems.\n\u003cbr\u003eMore than 5 years or 80,000 km since new*\n\u003cbr\u003e*Varies depending on vehicle usage.\n\u003cbr\u003eTotal Length: 530\/470mm\n\u003cbr\u003eTotal length is measured from the gasket to the tip of the connector.\n\u003cbr\u003eCompatible Manufacturer: Mazda\n\u003cbr\u003eCompatible Genuine Part Number: LF2L-18-8G1C\u003c\/p\u003e\n\n\u003cp\u003e■Image Disclaimer\n\u003cbr\u003e*Images are for illustration purposes only.
