NTK 25699 Oxygen Sensor Fits select: 2006-2011 HONDA CIVIC

NTK Oxygen Sensors 25699 OE Type 4-Wire A/F Sensor Oxygen (O2) Sensors are used in modern automobiles to control the fuel and ignition systems to optimize a car’s performance in the areas of emissions and fuel economy. Sensors are located before and after the catalytic converter to check on the amount of oxygen in the exhaust. The sensor sends signals to the car’s on-board computer, which then can adjust several variables, including air/fuel ratio and timing, in order to bring the engine into the optimum operating range.Each NTK Oxygen (O2) Sensor isExtensively Tested During Manufacture to Guarantee Quality and ReliabilitySupplied With a Factory-Fitted OEM Connector for Easy InstallationPrecision manufactured with a sensing element incorporating NTK’s premier technical ceramicsOxygen (O2) Sensors should be tested at each tune-up.
