Dodge Diplomat Catalytic Converter

About

A catalytic converter is a device that reduces the toxicity of emissions produced by the internal combustion engine. It contains a catalyst that converts harmful vehicle emissions like hydrocarbons and carbon monoxide into less toxic substances such as water vapor and carbon dioxide. Catalytic converters also contribute in controlling air pollution by burning unburned gas in the tail pipe. A damaged catalytic converter will result in poor exhaust emission which is a health hazard. If your car's engine does not run properly over a long period of time, the catalytic converter may become hot or corroded with foreign substances such as oil, causing it to be ineffective. If this should happen, the catalytic converter must be replaced. Auto Parts Network carries high quality automotive parts at low prices. Hide
