Bosch 17307 Premium Wideband Air/Fuel Ratio Oxygen Sensor

The Bosch 17307 is a premium OE-type wideband air/fuel ratio oxygen sensor designed for pre-catalyst installation. This advanced sensor utilizes a sophisticated sensing element that precisely measures the amount of oxygen in the exhaust, providing proportional signals to the vehicle's ECU rather than simply switching between rich and lean conditions.

Key Features:

• Wideband air/fuel ratio sensing technology for precise exhaust oxygen measurement
• 5-wire heated design with fast-acting heater element for quick operating temperature
• 18mm thread diameter with anti-seize compound pre-applied for easy installation
• 21.5-inch wire length with true direct-fit OE connectors and harness
• Zirconium sensing element for accurate, long-lasting performance
• Double laser-welded stainless steel body for complete submersion protection
• 100% functionally tested (protection tube may show seared appearance from testing)

Bosch invented the automotive oxygen sensor in the late 1960s and remains the world's leading supplier of OE oxygen sensors. This sensor is engineered to restore proper air/fuel mixture control, reduce harmful emissions, and optimize fuel economy. The robust sensor design ensures longevity, while the pre-coated threads and direct-fit connectors make installation simple and hassle-free.
