O2 sensors play an important role in detecting the oxygen concentration in exhaust gas and providing feedback to the ECU*1.\n\u003cbr\u003eNTK O2 sensors detect the oxygen concentration in the exhaust gas and feed it back to the ECU so that the fuel-air mixture ratio (air-fuel ratio) is at the optimal stoichiometric air-fuel ratio \"λ (lambda) = 1*2\". The ECU uses the signal from the O2 sensor to control the air-fuel ratio near the stoichiometric value, which most effectively purifies harmful substances in the exhaust gas. If the fuel is too rich compared to the stoichiometric air-fuel ratio, it thins the fuel; if it is too lean, it enriches the fuel. Thus, NTK O2 sensors are crucial components for reducing harmful substances in exhaust gas.\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 is rich or lean compared 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. This allows for more precise engine control than with zirconia O2 sensors. It also enables engine control outside of 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 after the engine key is turned on) through an integrated structure of the element and heater.\n\u003cbr\u003e【Need for Replacement】\n\u003cbr\u003eO2 sensors are constantly exposed to exhaust gas exceeding 600°C and accumulate combustion byproducts, operating in a very harsh environment.\n\u003cbr\u003eUsing a degraded 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 conditions.\n\u003cbr\u003eTotal length: 350mm\n\u003cbr\u003eThe total length is the length from the gasket to the tip of the connector.\n\u003cbr\u003eHeat shields and other parts are included; please use them as is without removing them.\u003c\/p\u003e\n\n\u003cp\u003e■Image Notes\n\u003cbr\u003e*Images are for illustration purposes only.
