Bosch 18090 Premium Wideband Air/Fuel Ratio Oxygen Sensor

The Bosch 18090 is a premium wideband air/fuel ratio oxygen sensor designed as a direct-fit OE replacement for select Infiniti and Nissan vehicles. Unlike traditional oxygen sensors that simply switch between rich and lean conditions, this wideband sensor precisely measures the exact amount of oxygen in the exhaust, providing the vehicle's ECU with continuous, highly accurate air/fuel mixture data across the full lambda range.

Key Features:

• Advanced wideband sensing element for exact air/fuel measurement
• 5-wire heated sensor design with OE-quality connectors and harness
• Robust sensor design increases sensor longevity
• Seared protection tube validated through 100% functional quality testing
• True direct-fit design with OE connectors for plug-and-play installation
• Planar ceramic construction for superior durability and fast response time

Bosch invented the automotive oxygen sensor and leads the way in sensor technology and innovation, with expertise spanning from overall sensor design to the critical ceramic element. This wideband sensor enables your vehicle's engine management system to optimize fuel mixture control, supporting improved fuel efficiency, better engine performance, and reduced exhaust emissions under all operating conditions.
