Everybody knows that our environment can be negatively affected by harmful exhaust gases from internal combustion engines. A catalytic converter is a device created to control your Audi A4’s emissions in the form of carbon monoxide and hydrocarbons. The chemical reaction takes place within the catalytic converter, or “cat” for short. This reaction is often referred to as “redox,” which stands for reduction-oxidation. When the exhaust heats the spongy precious-metal element inside the steel casing, it starts to catalyze harmful pollutants turning them into less harmful gases.

Since 1975, the use of catalytic converters in the U.S. became a legal requirement on all gasoline-powered autos. Catalytic converters provide a huge service for mother nature while reducing the greenhouse effect thus protecting the environment. Although, catalytic converters, just like all automotive parts, wear out and may get clogged, with such tell-tale signs as poor acceleration, lower fuel efficiency, and harder starts being among some of the most obvious ones. We carry a wide range of high-quality Audi A4 catalytic converters & components offered at an affordable price, so you can easily restore the emission control system of your car.
