Catalytic converters are used to convert toxic exhaust emissions from an internal combustion engine into non-toxic substances. They come in two types, the first - a two-way or oxidation catalytic converter that oxidizes carbon monoxide to carbon dioxide and hydrocarbons to carbon dioxide and water. This type is widely used on diesel engines but was eventually superseded by three-way converters. The three-way catalytic converters have been used since 1981 and work by reducing nitrogen oxides to nitrogen and oxygen, oxidizing carbon monoxide to carbon dioxide, and unburnt hydrocarbons to carbon dioxide and water.
Benchmark Catalytic Converters are more than up to the job. Considered to be the industry's standard replacement catalytic converter, it is also the recognized leader in fitment and durability.
