What Stands Out
Product Details
- [INNOVATIVE TECHNOLOGY] - Every Bosch Oxygen Sensor benefits from the technological and manufacturing experience gained from decades of production since first inventing the Oxygen Sensor in the late 1960's, ensuring long-lasting performance
- [FACTORY TESTED] - Each sensor meets Bosch's rigorous standards for quality and performance and undergoes a fully functional quality test before leaving the factory to ensure operation within design specifications
- [STAINLESS STEEL BODY] - Stainless steel body is totally submersible and sealed tight to protect against damage from exhaust emissions - ensuring longer sensor service life
- [UNIVERSAL FIT] - Includes OE Smart Link Connector that requires no soldering and two feet of sensor wire to allow maximum replacement of worn or damaged harnesses - the ideal solution when factory connectors aren't usable
- [FOR USE WITH DAMAGED VEHICLE SIDE CONNECTORS/CABLES] - Bosch Universal Oxygen Sensors are designed for situations where the original vehicle side connectors/cables are too damaged to be reused with an exact fit oxygen sensor
- Compatible with select mid 1980's to early 2000's vehicles from many domestic and asian manufacturers (Note: verify specific fitment details, including year, make, model, engine, and sensor position, with fit checker above)
