Infiniti QX4 Oxygen Sensor
Your QX4 is a prized possession.
It's not a regular occurrence that you realize that you have to buy a replacement Oxygen Sensor for your vehicle. While it may not be difficult to find replacement parts for Infiniti vehicles, these days only the absolute best are required to maintain your automobile. When your Infiniti QX4 rolled off the assembly line, it was destined for a person with discerning taste who values unique styling in their automobile. The vehicle in your driveway is head and shoulders above the rest when it comes to all the cars, trucks, and SUVs in today's marketplace.
The function and purpose of Oxygen Sensor.
Achieving maximum power and fuel efficiency with your car or truck depends on how well you maintain your engine and exhaust parts. The fuel-injection system on your Infiniti QX4 is runs on signals sent by your ECU which relies on input from the oxygen sensors. Your Infiniti QX4 oxygen sensors sit in the exhaust manifold, exhaust pipes, and catalytic converter and analyze the quality of the exhaust gases to determine how well your fuel delivery and emissions reduction parts are working. When oxygen sensors fail your car will not get the best fuel economy or produce enough horsepower, and it will likely be emitting an excess of hazardous exhaust.
There's no reason to delay... fix it today.
Don't let a Oxygen Sensor repair spell the end of your car, truck, or SUV, and don't risk lowering its resale value by using anything but the highest quality repair parts.
