Bosch 18004 Premium Oxygen Sensor

The Bosch 18004 Premium Oxygen Sensor is engineered to optimize fuel economy while reducing harmful emissions. As the inventor of the oxygen sensor, Bosch brings decades of expertise to this direct-fit replacement that meets or exceeds OE specifications. The sensor includes an OE-style connector for straightforward installation without splicing or modifications.

Advanced Ceramic Technology:

This oxygen sensor utilizes Bosch's innovative planar and thimble ceramic technologies for superior performance and durability. The planar design features a multi-layer construction with a dedicated heater layer for faster light-off times, an air duct layer that creates a reference air chamber, and a sensor layer with precisely printed electrodes. The inner reference air electrode and outer exhaust gas electrode work together with a porous protective layer that shields against corrosive exhaust gases.

Key Features:

• Base ceramic probe constructed from Zirconium and Yttrium provides 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 includes fine particle filter to prevent electrode contamination and coarse particle filter for protection against exhaust gas and chemical contamination
• Direct-fit design with OE connector for easy, plug-and-play installation
• Engineered to OE specifications for reliable operation and emissions compliance

Bosch oxygen sensors deliver the precision and reliability needed for proper engine management, ensuring your vehicle runs efficiently while meeting emissions standards.
