Featuring a double laser-welded stainless steel body and rapid heater technology, it ensures optimal engine performance and reduced emissions. Designed for select Chrysler Crossfire and Mercedes-Benz models, it offers true OE fitment and easy installation with pre-coated anti-seize threads. ## Description 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 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. ## Features - [INNOVATIVE TECHNOLOGY] - 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 performance - [FACTORY TESTED] - Seared appearance of protection tube is a result of a 100 percent fully functional quality test to ensure every Bosch manufactured sensor meets Bosch's rigorous standards for quality and performance - [STAINLESS STEEL BODY] - Exclusive double laser-welded stainless steel body is totally submersible and sealed tight to protect against damage from exhaust emissions - ensuring longer sensor service life - [FAST ACTING HEATER] - 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 - [READY TO INSTALL] - 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 easy - Compatible with select vehicles (Note: engine may affect fitment - verify specific fitment details, including sensor position, with fit checker above): CHRYSLER: 2004-08 Crossfire; MERCEDES-BENZ: 2001-03 ML320, 2003-05 ML350, 2001 ML430 - Compatible with (continued): MERCEDES-BENZ: 2002-05 ML500, 2001-04 SLK230 ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Bosch | | Item dimensions L x W x H | 2.2 x 1.97 x 5.83 inches | | Material | Stainless Steel | | Item Weight | 0.23 Pounds | | Style | Oxygen Sensor | | Mounting Type | Flange Mount | | Output Type | Push-Pull | | Specific Uses For Product | automotive | | UPC | 028851161237 | | Global Trade Identification Number | 00028851161237 | | Manufacturer | BOSCH | | Model | Oxygen Sensor | | Item Weight | 3.68 ounces | | Product Dimensions | 2.2 x 1.97 x 5.83 inches | | Item model number | 16123 | | Is Discontinued By Manufacturer | No | | Exterior | Machined | | Manufacturer Part Number | 16123 | | OEM Part Number | 0015403717 | ## Product Details - **Brand:** Bosch - **Item dimensions L x W x H:** 2.2 x 1.97 x 5.83 inches - **Material:** Stainless Steel - **Item Weight:** 0.23 Pounds - **Style:** Oxygen Sensor ## Images ![16123 Premium Original Equipment Oxygen Sensor - Compatible with Select Chrysler Crossfire; Mercedes-Benz ML320, ML350, ML430, ML500, SLK230 - Image 1](https://m.media-amazon.com/images/I/61AE3mueW-L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Authentic Bosch 16123Β O2 Sensor with laser-etched BOSCH logos & save $200 without the Mercedes Logo! *by S***5 on Reviewed in the United States on December 1, 2023* The BOSCH trademarks are laser etched on this authentic OEM Bosch 16123 Air Fuel Sensor OE QUALITY REPLACEMENT SENSOR; OE STYLE; CALIF sensor. This sensor was a perfect fit for the 2004 W163 2004 Mercedes ML350 Downstream. You don't need a special tool to remove O2 sensors. 22mm wrench is perfect.After properly testing fuses, relays, o2 sensor voltage, and fuel trim, only replace O2 sensors. Rather than spending $70 on o2 sensors, simply blow a $2 fuse. In the worst-case scenario, both blocked catalytic converters and good oxygen sensors are possible. Standard methods for assessing whether or not the catalytic converter is clogged include a vacuum gauge and back pressure testing. A catalytic converter that has become clogged or damaged cannot be fixed. You must replace catalytic converter $700 or your California Smoke Test will fail.Use the Nickel-Based Anti-Seize Lubricant with the sensors to ensure that the BoschO2 sensors can be readily removed during subsequent service. Inspect the oxygen sensor and fuel trim if your engine is over 60,000-100,000 miles old and exhibiting rough idling, loss of power, poor acceleration, engine misfires, or even stalling. Failure of oxygen sensors affects all important engine functions, including air-fuel ratio, combustion intervals, and engine timing.A healthy O2 sensor has a voltage range of 200 to 800 millivolts, or 2. to 8. volts on your meter. Your sensor has failed if the reading is fixed in one area or alternates erratically between high and low. The oxygen sensor compares the oxygen levels in the air to those in the exhaust. It transmits information to the engine computer, which modifies the air intake and fuel. The O2 sensor, like other auto parts, has a limited lifespan. It is normally between 30,000 and 100,000 miles, depending on the type of sensor. If your O2 sensors are malfunctioning, you will fail the California Smoke Inspection required to renew your license. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Bosch the best !! *by L***T on Reviewed in the United States on May 19, 2021* Bosch has the best products when it comes to o2 sensor upstream and downstream !!!I replaced all of my o2 sensor on my2003 mercedes-benz ml320 and it runs great!!! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great price for a great product *by E***. on Reviewed in the United States on May 18, 2021* Got the P0130 error code on my Mercedes SLK230 twice so I decided to change the Oxygen sensor. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/29225259-16123-premium-original-equipment-oxygen-sensor-compatible-with-select-chrysler](https://www.desertcart.de/products/29225259-16123-premium-original-equipment-oxygen-sensor-compatible-with-select-chrysler) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-04-22*
