Review on LSAILON Downstream For234 4190 2011 2013 Pathfinder by Stephen Schmidt

My mechanic installed this upstream O2 sensor quickly and advised me to use premium gas occasionally or whenever I can. Now my 2011 Nissan Murano SV has been running great for 2 days with over 132,000 miles. The engine light is on again! The engine diagnostics showed a problem with another sensor - AF 1. The mechanic said that he had to change the settings of the car to recognize the new part. He diagnosed other possible problems with his tool and nothing else came up. He sent me on my happy way! I'll definitely update the stars if the thing lasts a few thousand more miles!
