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

When you're working on your 2002-2004 Acura RSX and need to replace the air-fuel ratio sensor, this direct-fit unit from NGK is what you're looking for. This sensor is a crucial part of your car's diagnostic system, helping to keep the engine running smoothly, get the best gas mileage, and cut down on emissions. Unlike older sensors that just signal if the mix is rich or lean, this wideband sensor gives the car's computer a precise reading, allowing for constant, accurate adjustments to the air-fuel mixture.

NGK, a major supplier to original equipment manufacturers, builds these sensors with an advanced ceramic element. This ceramic core features a three-stage protective coating that resists contaminants and deposits, which can poison the sensor and lead to failure. This construction helps ensure reliable performance and longevity, keeping your engine running at its best.
