NGK 2015-13 Acura ILX OE Type 4-Wire A/F Sensor

NGK is well-known for making reliable ignition and sensor components for a wide range of vehicles. This OE Type 4-Wire Air/Fuel Ratio Sensor is built to meet the original equipment specifications for your 2006-2015 Honda Civic, as well as compatible Acura ILX, Honda Accord, and Honda HR-V models. An air/fuel ratio sensor, also known as a wideband oxygen sensor, plays a crucial role in your engine's performance by precisely measuring the amount of oxygen in your exhaust stream. This data is critical for the engine control module (ECM) to adjust the fuel injection timing and ensure the optimal air-to-fuel mixture for combustion.

When your air/fuel ratio sensor is working correctly, you can expect your engine to run smoothly, maintain good fuel economy, and produce lower emissions. If this sensor starts to fail, you might notice a check engine light, rough idling, decreased gas mileage, or even a failed emissions test. This NGK sensor is designed as a direct replacement, meaning it should install without needing any modifications, making it a solid option for restoring your engine's performance and efficiency.
