The modern Mercury Sable Catalytic Converter is not the one installed on your old vintage-1970's Merc. That old device was cumbersome, filled with hundreds of lead pellets, and drained the power out of your engine like a leaky bathtub. Today's Mercury Sable Catalytic Converter is a sleek, lightweight, high-tech piece of equipment that actually improves your car's performance while ridding the exhaust of toxic substances.

It's part of today's sophisticated exhaust systems that work with the fuel system to reduce air pollution and use fuel more efficiently. Inside your catalytic converter is a ceramic element, coated with a compound of platinum and palladium.

This is the actual "catalyst," which "converts" exhaust by breaking the molecular bonds of deadly carbon monoxide and nitrous oxide and recombines them into relatively innocuous CO2 and water vapor. It isn't a completely perfect solution, since excess CO2 has been linked by the scientific community to global climate change, however, it has been a major step forward in creating a more breathable atmosphere. Now, if you're engine is out of tune, or running too rich for some reason, a bit of unburned gasoline may make its way down into the catalytic converter and burn up inside the unit. In the old days, this resulted in a "backfire." Today, it may result in major damage to your catalytic converter, melting the ceramic and platinum components. An easy way to check for this is by removing the oxygen sensor. Rev the engine up to about 4000 RMP; a whistling sound tells you the device is clogged.If that's the case, count on us for the best price on a new Mercury Sable Catalytic Converter.
