Great cars and trucks like your Century need great parts.

Select Your VehicleAuto enthusiasts appreciate the good looks built into each Buick, and know that only the best repair Century parts will suffice when maintenance needs to be done. When your Buick Century left the factory, it was destined for a person with discerning taste who values a trusted name in their automobile. Make no mistake, you didn't buy your Century unless you understood you would be getting efficiency and fun both impeccably combined into one car, truck, or SUV. The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles in today's marketplace.

The function and purpose of Oxygen Sensor.

Reducing harmful emissions that come from your car or truck depends on the quality and performance of the parts you use. The fuel-injection system on your Buick Century is runs on signals sent by your ECU which relies on input from the oxygen sensors. Your Buick Century 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 engine will not be operating as it should; lacking in power and lowering gas mileage, and it will likely be emitting an excess of hazardous exhaust.
