Infiniti Q45 Oxygen Sensor

Why you drive your Q45.

Anyone who operates a Infiniti knows that when it comes to repairing their car, truck, or SUV only the absolute best replacement parts will do. Your Infiniti dealership isn't the only place to buy genuine or original equipment quality parts to repair your Q45. Car aficionados know that a reliable name is built into each Infiniti, and understand that only top quality replacement Q45 parts will suffice when maintenance needs to be done. You bought your Q45 because its a reputation for safety and Japanese engineering appealed to your senses; so why would you settle for second best when it comes to superior quality auto parts?

Why Oxygen Sensor replacement is so important.

Getting the most out of your car or truck depends on your use of properly functioning air and fuel delivery parts. The fuel-injection system on your Infiniti Q45 is runs on signals sent by your ECU which relies on input from the oxygen sensors. Your Infiniti Q45 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 engine will not be operating as it should; lacking in power and lowering gas mileage, and emissions from your tailpipe may be in excess of legal levels.

There's no reason to delay... make your purchase while supplies last.
