Shop Subaru Baja Replacement Catalytic Converter

The internal combustion engine produces carbon monoxide, hydrocarbons and nitrogen oxides, all of which are toxic air pollutants. Your Subaru Baja's catalytic converter is a piece of equipment that actually interacts chemically with these gases, converting them into far less toxic carbon dioxide, nitrogen and water. The active parts of the catalytic converter are made from the heavy metals platinum, rhodium and palladium. These metals are housed in a ceramic casing that can crack if it overheats. If your catalytic converter malfunctions, the check engine light will go on in your dashboard. You may actually hear the broken ceramic parts of the converter rattle. Emissions may contain an excess of hydrogen sulfide that smells like rotten eggs. Your vehicle will not be able to pass the emissions control test necessary to reregister it. You can buy a replacement catalytic converter for your Subaru Baja at PartsGeek.com.
