Select Your VehicleThe vehicle in your driveway is head and shoulders above the rest when it comes to all the vehicles these days. Lexus automobile owners have become used to a certain level of sporty handling when driving their IS300 around town. Anyone who operates a Lexus knows that when it comes to maintaining their car, truck, or SUV only the highest quality replacement parts will do. Make no mistake, you bought your IS300 because you wanted to buy best-in-class service and a trusted brand both impeccably combined into one automobile.

What Catalytic Converter does for your vehicle.

Getting the most out of your car or truck depends on how well you maintain your engine and exhaust parts. Your Lexus IS300 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 change the harmful emissions of your Lexus IS300 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.

The things this company has to make it special.
