The function and purpose of Catalytic Converter.

Getting the most out of your car or truck depends on how well you maintain your engine and exhaust parts. Your GMC Sierra 3500 Classic catalytic converter is the result of about a decade of engineering that took place in the 1960s and 70s. There are a host of precious metals, mostly platinum, in the catalytic converter that turn the carbon monoxide and hydrocarbons that your GMC Sierra 3500 Classic produces into harmless molecules of carbon dioxide, oxygen, and some water. Thanks to this chemical reaction, automakers could now curb their contribution to air pollution, which is why every vehicle made today has a catalytic converter.

You've tried the rest, now try the best.
