Buick Regal Catalytic Converter

Your Regal is a prized possession.

Anyone who operates a Buick knows that when it comes to maintaining their vehicle only the highest quality replacement parts will do. Buick car, truck, or SUV enthusiasts have grown accustomed to a certain level of dependability when driving their Regal around town. When your Buick Regal rolled off the assembly line, it was destined for a person with discerning taste who values a trusted name in their automobile. It's not a regular occurrence that you find yourself in need of a replacement Catalytic Converter to repair your vehicle.

What Catalytic Converter does for your vehicle.

Getting the most out of your car or truck depends on the quality and performance of the parts you use. Your Buick Regal catalytic converter has been installed thanks to a federal mandate that is decades old. Inside every catalytic converter are cells made from platinum and/or rhodium arranged in a honeycomb pattern that change the harmful emissions of your Buick Regal from carbon monoxide and hydrocarbons to carbon dioxide and water. This process revolutionized automakers' ability to improve air quality, which is why every vehicle made today has a catalytic converter.
