Lexus RX300 Oxygen Sensor

Why you drive your RX300.

Anyone who operates a Lexus knows that when it comes to repairing their vehicle only the absolute best replacement parts will do. When your Lexus RX300 was born, it was destined for a person with discerning taste who prioritizes Japanese engineering in their automobile. Your Lexus dealership isn't the only place to locate genuine or original equipment quality repair parts to fix your RX300. Car aficionados appreciate the reliability built into each Lexus, and know that only top quality replacement RX300 parts will suffice when repairs are needed.

Why Oxygen Sensor replacement is so important.

Getting the most out of your car or truck depends on how well you maintain your engine and exhaust parts. The fuel-injection system on your Lexus RX300 is runs on signals sent by your ECU which uses data collected by your oxygen sensors. Your Lexus RX300 oxygen sensors use the particulates in the exhaust gas to determine if the fuel is too rich, too lean, or if the catalytic converter isn't working. When oxygen sensors fail your car will not get the best fuel economy or produce enough horsepower, and emissions from your tailpipe may be in excess of legal levels.

You've tried the rest, now try the best.
