NGK 2012-07 Acura RDX OE Type 4-Wire A/F Sensor

This NGK 4-wire Air/Fuel ratio sensor is built to OE specifications for your 2007-2012 Acura RDX. It's a direct replacement for the original part, meaning it's designed to connect and function just like the factory sensor. A properly working A/F sensor is crucial for your engine's computer to accurately measure the amount of oxygen in the exhaust, which helps it fine-tune the fuel injection for the best balance of power and fuel economy.

NGK is a well-known name in ignition and sensor technology, and this sensor uses a robust construction to handle the high temperatures and harsh environment of the exhaust system. The four-wire design allows for both upstream oxygen sensing and heater circuit control, ensuring quick response times and accurate readings from a cold start. Replacing a faulty A/F sensor can help resolve issues like poor fuel mileage, rough idling, and check engine lights related to fuel trim.
