Infiniti QX4 Oxygen Sensor

Great cars and trucks like your QX4 need great parts.

Obviously, you didn't buy your QX4 unless you wanted to buy best-in-class service and a trusted brand both impeccably combined into one vehicle. Auto enthusiasts know that luxury is built into each Infiniti, and know that only the best repair QX4 parts will suffice when maintenance needs to be done. The vehicle in your driveway symbolizes the best in class when it comes to all the vehicles in today's marketplace. Your Infiniti dealership isn't the only place to locate trusted parts to repair your QX4.

What Oxygen Sensor does for your vehicle.

Achieving maximum power and fuel efficiency with your car or truck depends on the quality and performance of the parts you use. The fuel-injection system on your Infiniti QX4 is heavily controlled by a computer which relies on input from the oxygen sensors. Your Infiniti QX4 oxygen sensors use the particulates in the exhaust gas to determine if the fuel is too rich, too lean, or if the catalytic converter isn't working. When oxygen sensors fail your engine will not be operating as it should; lacking in power and lowering gas mileage, and emissions from your tailpipe may be in excess of legal levels.

High quality parts, great prices, staff that want to please you.
