Achieving maximum fuel efficiency while reducing emissions on your car or truck depends on the quality and performance of the parts you use. Your BMW 540i 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 turn the carbon monoxide and hydrocarbons that your BMW 540i produces into harmless molecules of carbon dioxide, oxygen, and some water. This process revolutionized automakers' ability to improve air quality, which is why every vehicle made today has a catalytic converter.
