Bosch 18098 Premium Wideband Air/Fuel Ratio Oxygen Sensor

The Bosch 18098 Premium Wideband Air/Fuel Ratio Oxygen Sensor delivers precise exhaust gas measurement for optimal engine performance and emissions control. As the inventor of the automotive oxygen sensor, Bosch brings decades of engineering excellence to this OE-quality replacement sensor.

Advanced Wideband Technology:

Unlike standard oxygen sensors that simply switch between rich and lean conditions, this wideband air/fuel ratio sensor utilizes a sophisticated sensing element to precisely measure the exact amount of oxygen in the exhaust stream. The ceramic element, constructed from zirconium and yttrium oxides, provides accurate readings from air/fuel ratios as rich as 9.0:1 to as lean as free air, enabling the vehicle's ECU to make precise fuel delivery adjustments.

Key Features:

• Advanced wideband sensing element for exact air/fuel measurement
• True direct-fit OE connectors and harness for easy installation
• Pre-coated threads with anti-seize compound right out of the box
• Robust sensor design increases longevity and reliability
• Seared protection tube from 100% functional quality testing
• Heated sensor with 5-wire design for faster response
• 18mm thread diameter with 22mm hex size
• Wire length: 521mm (20.5 inches)

Performance Benefits:

This premium oxygen sensor helps maintain optimal engine performance, improve fuel efficiency, and reduce harmful emissions. A failing oxygen sensor can cause reduced gas mileage, rough idle, poor acceleration, and emissions test failure. The Bosch 18098 restores proper air/fuel mixture monitoring to keep your engine running at peak efficiency.

Original Equipment Quality:

Bosch is the world's leading supplier and original equipment manufacturer of oxygen sensors. Each sensor undergoes rigorous quality testing and is built to the same exacting standards as original equipment, ensuring reliable performance and long service life. Backed by a 12-month warranty.
