SENSOR O2 12MM M8 17+ GRY

Front 12mm oxygen sensor Gray connector 52", 4 wire Meets or exceeds OE specifications Made in the U.S.A. Precision made consisting of a ceramic body made of stabilized zirconium dioxide, surface coated with gas-permeable platinum electrodes and a porous ceramic to aid the prevention of erosion due to contamination and particulates in the exhaust gases Slow oxygen sensors can cause a drop in fuel economy of 10-15%, excessive exhaust emissions and poor drivability Life expectancy of an average oxygen sensor in a properly tuned engine is typically 30,000 - 50,000 miles
