Park Avenue catalytic converters make the pollutants in exhaust gas less toxic through a redox reaction. When exhaust becomes trapped in front of the converter, it creates backpressure that causes your engine to stall and your car to jerk. A high-performance catalytic converter for Buick Park Avenue from AutoZone eliminates these issues. Order now and get it today with Same Day Store Pickup (in most cases), or receive Free Shipping on $75 or more. Remember to check out our Loan-a-Tool Program for any equipment you need to install the new converter.
