12 mm Narrow Band O₂ Sensor

12 mm Narrow Band O₂ Sensor

Precision manufactured with a ceramic body of stabilized zirconium dioxide, surface coated with gas-permeable platinum electrodes and a porous ceramic to help prevent erosion due to contamination and particulates in the exhaust gases

Slow reading oxygen sensors can cause a drop in fuel economy of 10-15%, excessive exhaust emissions and poor drivability

All sensors meet or exceed OE specifications

Made in the USA

Life expectancy of an average oxygen sensor in a properly tuned engine is typically 30,000 - 50,000 miles.
