Select Your VehicleYour Buick dealership isn't the only place to locate genuine or original equipment quality repair parts to fix your Regal. Anyone who owns a Buick knows that when it comes to maintaining their vehicle only the highest quality replacement parts will do. Buick automobile owners have grown accustomed to a certain level of reliability when driving their Regal around town. You picked your Regal because its reliability and economical pricing appealed to your senses; so why would you settle for anything but the best when it comes to superior quality auto parts?

What Oxygen Sensor does for your vehicle.

Reducing harmful emissions that come from your car or truck depends on how well you maintain your engine and exhaust parts. The fuel-injection system on your Buick Regal is runs on signals sent by your ECU which relies on input from the oxygen sensors. Your Buick Regal 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 emissions from your tailpipe may be in excess of legal levels.
