Bosch 0258017098 Premium Wideband Oxygen Sensor

The Bosch 0258017098 (also known as part number 17098) is a premium wideband air/fuel ratio oxygen sensor designed to deliver precise exhaust monitoring and optimal engine performance. This OE-quality sensor utilizes advanced sensing technology to measure the exact amount of oxygen in exhaust gases rather than simply switching between rich and lean conditions, providing your vehicle's ECU with proportional, real-time data for superior fuel management.

Key Features:

• Wideband air/fuel ratio technology for precise oxygen measurement and optimal air-fuel mixture control
• True direct-fit OE connectors and integrated wiring harness for easy, plug-and-play installation
• Threads pre-coated with anti-seize compound right out of the box for hassle-free installation
• Exclusive double laser-welded stainless steel body that is fully submersible and sealed for maximum durability
• Fast-acting heater element reaches operating temperature within seconds for quick sensor activation
• 100% factory tested with seared protection tube appearance, ensuring every sensor meets Bosch's rigorous quality standards
• Designed for upstream position (before catalytic converter) on Bank 1 (cylinders 1-3)
• 55.1-inch wire harness length provides flexibility for proper routing

Bosch invented the automotive oxygen sensor in the late 1960s and remains the world's leading supplier and OEM manufacturer of oxygen sensors. With over one billion sensors produced, Bosch oxygen sensors are trusted by vehicle manufacturers worldwide for their precision, reliability, and long service life. This sensor helps improve fuel economy, reduce harmful emissions, and maintain optimal engine performance by ensuring the ECU receives accurate lambda data for precise fuel adjustments.

Replacing a worn oxygen sensor at manufacturer-recommended intervals prevents long-term engine damage, reduces CO2 emissions, and saves money at the pump by maintaining proper combustion efficiency. Cross-references to OEM part number 11787558055.
