Bosch 13115 OE Type Upstream Oxygen Sensor 4-Wire Planar

The Bosch 13115 is a premium OE-type upstream oxygen sensor (O2 sensor) engineered to deliver factory-correct fit and performance. As the company that invented the automotive oxygen sensor, Bosch brings unmatched expertise to every unit — this planar-style, 4-wire heated sensor is built to meet or exceed original equipment specifications for accurate exhaust gas monitoring and reliable engine management feedback.

The oxygen sensor continuously measures oxygen content in exhaust gases and relays that data to the engine control unit (ECU), which uses it to optimize the air/fuel mixture for peak combustion efficiency, reduced emissions, and maximum catalytic converter life. A failing O2 sensor can trigger check engine codes such as P0131, P0132, or P0133, cause poor fuel economy, and accelerate catalytic converter wear.

Key Features:

• OE Type Direct Fit — Includes a true OE-style connector and wiring harness for plug-and-play installation with no splicing required
• 4-Wire Heated Planar Design — Integrated fast-acting heater brings the sensor to operating temperature quickly for accurate readings even during cold starts
• Zirconium Ceramic Element — Precision sensing material delivers a stable 0–1V signal output for accurate air/fuel ratio control
• Double Laser-Welded Stainless Steel Body — Fully submersible, sealed construction protects against contamination, extreme heat, and engine vibration
• Pre-Coated Threads — Anti-seize compound applied at the factory for easier installation and future serviceability
• Seared Protection Tube — Shields the ceramic element and ensures long-term sensing accuracy
• 100% Functionally Tested — Every sensor is subjected to a 1,000°C functional test and leak test before leaving the factory
• 18mm Thread Diameter — Standard thread size for direct, bolt-in fitment
• Wire Length: 620mm (24.5 inches)
• 12-Month Warranty
