Your cart is empty.Every Bosch Oxygen Sensor benefits from the technological and manufacturing experience gained from decades of production, since first inventing the Oxygen Sensor in the late 1960's, ensuring long-lasting, superior performance that you can count on. Bosch Oxygen Sensors are 100% tested for full functionality, resulting in a seared appearance of the protection tube, to ensure every Bosch manufactured sensor meets Bosch's rigorous standards for quality and performance. Exclusive double laser-welded stainless steel body is totally submersible and sealed tight to protect against damage from exhaust emissions — ensuring a longer sensor service life. Fast-acting heater optimizes sensor operation on Planar and 3, 4, and 5 wire Thimble type sensors allowing the oxygen sensor to reach its operating temperature quicker – within seconds – for optimum performance. True Direct-fit OE connectors and harnesses, along with threads pre-coated with anti-seize compound right out of the box, make installation simple and hassle-free. It’s critical that oxygen sensors are replaced at the suggested intervals provided by vehicle manufacturers before the sensor fails. Following the recommendations will prevent long term damage to a vehicle’s engine, reduce harmful carbon dioxide (CO2) emissions and save money when refueling your vehicle.

Looking for a reliable and cost-effective solution for your faulty oxygen sensor? Look no further than the genuine Bosch 16123! Here's a breakdown of its features, installation tips, and why it's a great choice for your vehicle:Genuine Bosch Quality with Savings:This sensor offers authentic Bosch quality at a significant price advantage compared to branded Mercedes alternatives. You can potentially save $200 without sacrificing performance. Laser-etched Bosch logos guarantee authenticity and ensure you're getting a genuine product.Technical Specifications:OE Replacement: This sensor is a direct OE (Original Equipment) replacement for the 2004 Mercedes-Benz ML350 (W163 chassis), specifically for the downstream sensor position.Californian Emissions (CARB Compliant): This sensor is certified to meet California's stricter emission standards, ensuring your vehicle passes smog tests.Ease of Installation and User Tips:Replacing the oxygen sensor can be done at home with basic tools. While a special O2 sensor removal tool might seem convenient, a 22mm wrench often suffices. If the sensor is stuck due to rust or corrosion, a penetrating lubricant like PB Blaster can help loosen it. Apply the lubricant, wait 15 minutes, and then attempt removal.Importance of Oxygen Sensor Replacement:A faulty oxygen sensor can lead to various performance issues, including rough idling, power loss, poor acceleration, engine misfires, and stalling. This sensor plays a critical role by measuring the oxygen content in the exhaust and sending this data to the engine computer. Based on this data, the computer adjusts the air-fuel mixture for optimal performance and emissions.Diagnosing the Problem:Before replacing the oxygen sensor, it's crucial to rule out other potential causes like blown fuses, faulty relays, or incorrect fuel trim values. These issues can sometimes mimic symptoms of a bad oxygen sensor.If you suspect a failing catalytic converter, a professional mechanic can use vacuum gauge and back-pressure testing to confirm the diagnosis. A clogged converter will require replacement and cannot be repaired.Proactive Maintenance:To prevent future removal difficulties, using a nickel-based anti-seize lubricant on the sensor threads during installation is recommended. This helps prevent seizing due to high engine temperatures.The lifespan of an oxygen sensor can vary between 80,000 and 100,000 miles, depending on driving conditions and fuel quality. Regularly inspecting your oxygen sensor and monitoring fuel trim values can help identify potential issues early.
