On April 22, 1970 there was a grassroots effort around the country to voice concerns about environmental pollution. There were more than 20 million demonstrators who turned out and it had the direct effect of causing the Federal government to pass the Clean Air Act later that year that called for a 90% reduction in vehicle exhaust. This lead to the installation of a catalytic converter in vehicles that in turn lead to a significant drop in air pollution.

The elements that make up the catalytic converter are destroyed by lead so that began the phase-out of leaded gasoline. By 1980, the phase-out of leaded gasoline, caused a 50 percent drop in blood-lead levels in humans.

The catalytic converter is installed in the vehicle’s exhaust line, before the muffler. It contains chemicals that change pollutants in gasoline to harmless gas as they pass through the catalytic converter and are expelled through the tailpipe into the atmosphere. The three main harmful emissions filtered through the Lexus ES300 Catalytic Converter are carbon monoxide, an odorless, colorless poisonous gas, hydrocarbons that come from evaporated unburned fuel and nitrogen oxide that irritates mucus membranes as well as contributing to smog and acid rain. The second stage of the Lexus ES300 Catalytic Converter is an oxidation catalyst further reduces hydrocarbons and carbon monoxide by burning them in another catalyst. Our catalytic converters are guaranteed to meet EPA policy and Conversion efficiency parameters. Before installing the Lexus ES300 Catalytic Converter, you need to make sure your engine is properly tuned. Otherwise, raw gasoline can enter the converter, raising the temperature so high that components of the converter can melt.You can order with confidence from our secure online store.
