Review NGK DIRECT FIT OXYGEN SENSOR Downstream Rear Acura 3.5l V6 fits MDX 2003–2006

Introducing the NGCK Oxygen Sensor 49MGKHBX, a high-performance replacement part designed specifically for the Acura MDX 2003-2006 with a 3.5L V6 engine and a downstream rear application. This oxygen sensor plays a crucial role in the vehicle's emission control system, ensuring optimal engine performance and fuel efficiency.

The 49MGKHBX is a zirconia oxygen sensor, which means it utilizes a zirconia ceramic element to measure the amount of oxygen present in the exhaust gases. This information is then sent to the vehicle's engine control module, allowing it to adjust the air-fuel mixture for efficient combustion. This results in reduced exhaust emissions, improved fuel economy, and a smoother engine operation.

This particular sensor is a downstream rear unit, meaning it is located closer to the exhaust manifold, where the exhaust gases have already been through the catalytic converter. The downstream position allows the sensor to measure the oxygen content in the exhaust gases after the catalytic converter has had a chance to reduce emissions.

The NGCK Oxygen Sensor 49MGKHBX is a direct fit replacement for the original equipment sensor on the Acura MDX 2003-2006 3.5L V6. It comes with all necessary hardware for installation, including a hex nut and gasket. The sensor housing and wiring harness are also designed to match the original equipment, ensuring a seamless installation process.

This sensor is manufactured to strict OEM specifications, ensuring the same level of precision and reliability as the original part. It is also backed by a 1-year warranty, providing peace of mind for the vehicle owner.

In summary, the NGCK Oxygen Sensor 49MGKHBX is a high-quality replacement part for the Acura MDX 2003-2006 with a 3.5L V6 engine and a downstream rear oxygen sensor application. It is a zirconia oxygen sensor designed to measure the oxygen content in the exhaust gases, ensuring optimal engine performance and fuel efficiency. This sensor is a direct fit replacement, comes with all necessary hardware, and is backed by a 1-year warranty.
