Bosch 18210 Premium OE Fitment Oxygen Sensor

The Bosch 18210 is a premium, OE-quality switching-type oxygen (O2) sensor engineered for precise air-fuel ratio monitoring. As the company that invented the automotive oxygen sensor, Bosch brings over 50 years of OE supply experience to every sensor in its lineup, delivering proven performance and reliability.

The O2 sensor continuously monitors exhaust oxygen content, feeding data to the engine control unit (ECU) to maintain the ideal air-fuel ratio of 14.7:1. A faulty or sluggish sensor can lead to decreased fuel economy, increased emissions, and reduced engine performance. The Bosch 18210 restores accurate closed-loop feedback for optimal engine operation.

Key Features:

• Switching-Type Design: Delivers precise air-fuel ratio feedback to the ECU for improved fuel efficiency and reduced emissions
• Stainless Steel Housing: Fully submersible, sealed body protects against exhaust heat, vibration, and corrosion
• Fast-Acting Integrated Heater: Brings the sensor to operating temperature in under 10 seconds for quick closed-loop control and improved cold-start performance
• Advanced Ceramic Element with TSP Coating: Resists contamination and extends sensor service life in demanding exhaust environments rated up to 1,880°F
• True Direct-Fit Connector: OE-matching connector and harness for a hassle-free, plug-and-play installation
• Pre-Coated Threads: Anti-seize compound applied at the factory for easier installation and future serviceability
• 100% Factory Tested: Every sensor undergoes full functional testing before leaving the factory to ensure it meets Bosch's rigorous quality standards
• OEM Cross-Reference: Replaces OE part number 226936CA0C
• Made in Japan

The Bosch 18210 upstream oxygen sensor is a direct-fit replacement that restores factory-level emissions control and engine efficiency, backed by the quality and engineering legacy of the world's leading O2 sensor manufacturer.
