NGK Acura RSX 2004-2002 Direct Fit 4-Wire A/F Sensor

This NGK Air-Fuel Ratio sensor is what you get when you need to get your 2001-2005 Honda Civic running right. It's a direct-fit, 4-wire sensor designed to work with your car's onboard diagnostic system, helping to keep your engine performing at its best, using fuel efficiently, and cutting down on harmful exhaust emissions.

Unlike older oxygen sensors that just tell the computer if the mix is rich or lean, this wideband sensor gives a precise reading. This allows your car's computer to make exact adjustments to the air-fuel mixture, keeping combustion as clean and efficient as possible. NGK, a major supplier to car manufacturers, uses advanced ceramic technology in their sensors. This particular sensor features a special overcoat that resists contamination and deposits, which helps prevent poisoning of the sensor element and keeps it working accurately for longer.
