Bosch 16089 Premium Oxygen Sensor

The Bosch 16089 Premium Oxygen Sensor is engineered to deliver optimal fuel economy while reducing harmful emissions. As the inventor of automotive oxygen sensors, Bosch brings decades of expertise to this direct-fit replacement sensor that meets or exceeds OE specifications.

Advanced Ceramic Technology:

This sensor utilizes Bosch's proprietary ceramic technology for superior performance and durability. Available in both planar and thimble designs, each sensor is built with precision-engineered layers that work together to provide accurate readings in harsh exhaust environments.

Planar Ceramic Technology Features:

• Integrated heater layer with printed electrical contacts and heating pattern for rapid warm-up
• Air duct layer that creates a reference air void in the assembly
• Multi-layer sensor design with inner and outer electrodes, plus a porous protective layer that shields against corrosive exhaust gases

Thimble Ceramic Technology Features:

• Base ceramic probe constructed from Zirconium and Yttrium for exceptional resistance to mechanical and thermal shock
• Patented Platinum Power Grid optimizes sensing capability for best-in-class performance and extended service life
• Dual-stage filtration system with fine and coarse particle filters to prevent electrode contamination and chemical damage

Installation and Compatibility:

This direct-fit oxygen sensor includes the OE connector for straightforward installation without splicing or modifications. The sensor is designed to plug directly into your vehicle's existing harness, making replacement quick and hassle-free.
