Based on the signal from the O2 sensor, if the fuel is rich compared to the stoichiometric air-fuel ratio, the ECU leans the fuel; if it is lean, it enriches the fuel. This controls the engine near the stoichiometric air-fuel ratio where harmful substances in the exhaust gas are most effectively purified. Thus, NTK O2 sensors are crucial 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 oxygen concentration difference 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 relative to the stoichiometric air-fuel ratio.\n\u003cbr\u003eFull-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 is possible than with zirconia O2 sensors. It also enables engine control outside the stoichiometric air-fuel ratio (λ=1), such as lean burn control. Furthermore, there are early activation type full-range air-fuel ratio sensors that maintain the characteristics of conventional full-range air-fuel ratio sensors while improving heat resistance and durability, and achieve early activation (operation starts within 5 seconds after 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 operate in extremely harsh environments where combustion products adhere to them.\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 conditions.\n\u003cbr\u003eOverall length: 350mm\n\u003cbr\u003eThe overall length is the length from the gasket to the tip of the connector.\n\u003cbr\u003eCompatible Manufacturer: Suzuki\n\u003cbr\u003eCompatible Genuine Part Number: 18213-57K01\u003c\/p\u003e\n\n\u003cp\u003e■Notes on Images\n\u003cbr\u003e*Images are for illustration purposes only.
