Hummer H3 Catalytic Converter

Keeping your H3 in top shape is your top priority.

Anyone who owns a Hummer knows that when it comes to repairing their car, truck, or SUV only the absolute best replacement parts will do. While it may not be difficult to buy replacement parts for Hummer vehicles, these days only the absolute best are required to fix your car or truck. When your Hummer H3 rolled off the assembly line, it was destined for a person with discerning taste who wants reliable GM engines in their automobile. You purchased your H3 because its off-road capability and reliable GM engines appealed to your senses; so why would you settle for second rate when it comes to great quality auto parts?

Why Catalytic Converter replacement is so important.

Reducing harmful hydrocarbons and noxious gases that come from your car or truck depends on how well you maintain your engine and exhaust parts. Your Hummer H3 catalytic converter is likely the single most effective pollution control device on production vehicles today. Inside every catalytic converter are cells made from platinum and/or rhodium arranged in a honeycomb pattern that change the harmful emissions of your Hummer H3 from carbon monoxide and hydrocarbons to carbon dioxide and 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.
