Designed for reliable exhaust monitoring, this oxygen sensor delivers fast, accurate feedback to the engine control system. ✅ 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 from contamination and particulates in the exhaust gases.
Slow‑reading oxygen sensors can reduce fuel economy by 10–15%, increase exhaust emissions, and cause poor drivability; replacing a slow sensor restores performance and efficiency. Typical life expectancy in a properly tuned engine is 30,000–50,000 miles. All sensors meet or exceed OE specifications and are made in the U.S.A.
