Brandon was on time for our appointment and was very thorough in explaining the entire process. I like that pictures were taken of my vehicle before the service was rendered and he showed me the old part that was being replaced and the new part and explained why it needed to be replaced.

Have had my cars services by Infiniti dealerships for over 10 years. This is the first time I have used another option. Something about being overcharged and being treated like a number lately by the delerships I don't like. Rocco arrived few minutes early, super polite guy, knows his stuff, no pressure, told me what I needed and when I needed it. Got down to business and got job done effortlessly while explaining the process. Left my garage clean, no spills definitely a five star. This is the first review I have written for anything and it's a five star. Excellent concept great service!!

All about Oxygen Sensor Replacement

With each new model year, manufacturers are adding more oxygen sensors to better manage engine operation. Some high performance engines have an oxygen sensor for each cylinder as well as one for the rear of each catalytic convertor. The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected (screwed) to the exhaust pipe, either in front or back of the catalytic converter. The front (upstream) sensors measure the amount of oxygen in the exhaust system. The purpose of the front oxygen sensor(s) is to measure how rich or lean the gases are as the gases exit the combustion chamber. Depending upon whether the exhaust gas is lean (high in oxygen content) or rich (low in oxygen content), the amount of fuel entering the engine is adjusted by the engine management computer to try and maintain an ideal mixture that produces the lowest emissions output from the catalytic convertor. Rear (downstream) sensors are located behind the catalytic converter. The purpose of the rear oxygen sensor(s) is to monitor the oxygen content of the exhaust gases leaving the catalytic convertor. If one or more of the oxygen sensors are faulty, your car may not pass the emissions test. If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter.
