Thanks to catalytic converters trucks have stopped running on leaded fuel. That’s one of the main reasons our air is cleaner today, even though there are more trucks on the road. Your Chevrolet K1500 catalytic converter takes the pollution created by your truck’s exhaust through a filter. This filter is normally a honeycomb - like structure made out of platinum, rhodium or palladium that acts as a catalyst to break up the pollutants and convert them into carbon dioxide, water vapor, and nitrogen. This chemical reaction going on in your truck every time you drive is the reason hydrocarbon emissions and lead in the air have gone down dramatically, while giving you the power and torque enhancement you want. It’s really pretty amazing when you think about it! Like most people, however, you don’t think about it much unless the catalytic converter is starting to fail. If yours is failing, a Catco K1500 catalytic converter specifically built for your 1996 - 1998 model is exactly what you need. Nothing will keep your Chevrolet running strong and smooth like a Catco. Get the performance you want and keep pollution from getting into the air we all breathe with a Chevrolet Catco catalytic converter.
