Review MERCEDES benz Genuine Remanufactured Injector

The **Mercedes-Benz 642-070-15-87-87 injector** is a precision-engineered fuel delivery component designed exclusively for high-performance diesel engines, specifically tailored to meet the demanding requirements of Mercedes-Benz OM642 and OM646 series engines, commonly found in models such as the **E320 CDI, E350 CDI, and E500 CDI** from the W211 and W212 generations. This injector is part of the **Common Rail Direct Injection (CRDI) system**, a sophisticated fuel injection technology that ensures optimal combustion efficiency, reduced emissions, and enhanced engine performance. Crafted from high-grade stainless steel and precision-machined to exacting tolerances, the **642-070-15-87-87** injector features a **piezoelectric actuator**, which delivers rapid and highly accurate fuel delivery with minimal lag, allowing for precise metering even at high engine loads. The internal needle valve operates with exceptional responsiveness, ensuring consistent spray patterns and fuel atomization, which is critical for maintaining power output and fuel economy while minimizing soot and particulate emissions. This injector is engineered to withstand the extreme pressures of the **common rail system**, typically operating at pressures exceeding **2,000 bar (29,000 psi)**, while also resisting corrosion and wear from the diesel fuel and combustion byproducts. The **OEM-quality build** ensures compatibility with the original engine management system, providing seamless integration with the vehicle s ECU (Engine Control Unit) for optimal performance tuning. Whether used in a **restoration project, performance upgrade, or replacement due to failure**, this injector guarantees reliability, durability, and adherence to Mercedes-Benz s stringent engineering standards. Its robust construction and advanced design make it an indispensable component for maintaining the integrity and efficiency of diesel-powered Mercedes-Benz vehicles.

### **Pros and Cons of buying a Mercedes-Benz 642-070-15-87-87 Injector**

#### **Pros:**

1. **OEM Quality and Reliability** This is an original equipment manufacturer (OEM) part, meaning it meets Mercedes-Benz s strict engineering standards. OEM injectors are designed to match the engine s specifications precisely, ensuring optimal performance and longevity.

2. **Compatibility and Fit** The part number (642-070-15-87-87) is specific to certain Mercedes-Benz models, particularly those with OM642 diesel engines (common in the 2006 2010 E320 CDI, E350 CDI, and ML350 CDI). Purchasing an OEM injector guarantees a perfect fit without modification.

3. **Durability and Longevity** OEM injectors are built to last the lifetime of the engine when properly maintained. They are less likely to fail prematurely compared to aftermarket alternatives, reducing the risk of costly repairs.

4. **Performance Consistency** Since these injectors are factory-calibrated, they deliver fuel in the exact quantity and pressure required, ensuring smooth engine operation, better fuel efficiency, and reduced emissions.

5. **Warranty Coverage** If purchased directly from Mercedes-Benz or an authorized dealer, the injector may come with a warranty, providing peace of mind against defects.

6. **Resale Value Protection** Keeping the vehicle with genuine OEM parts helps maintain its resale value, especially for high-mileage or classic Mercedes-Benz models.

#### **Cons:**

1. **High Cost** OEM injectors are significantly more expensive than aftermarket alternatives. Prices can range from **$500 to $1,500 per injector**, depending on availability and demand. For a set of four injectors, the total can exceed **$2,000 $6,000**, making repairs or replacements a major financial burden.

2. **Long Lead Times** OEM parts, especially for older or discontinued models, can be difficult to source quickly. Some dealers may require weeks or even months to obtain the part, delaying repairs.

3. **Limited Availability** As engines age, Mercedes-Benz may discontinue production of certain injectors. This can make finding a replacement challenging, particularly if the part is no longer in stock.

4. **Potential for Counterfeit Parts** Buying from unauthorized sellers (e.g., eBay, third-party online marketplaces) increases the risk of receiving fake or low-quality OEM parts. Always verify the seller s authenticity to avoid receiving substandard injectors.

5. **Maintenance Dependency** Even OEM injectors require regular maintenance (e.g., cleaning, fuel system checks) to prevent clogging or failure. Neglecting maintenance can lead to premature wear, negating the benefits of using genuine parts.

6. **Labor Costs** Replacing injectors is a complex job that typically requires professional installation, especially if it involves recalibrating the engine management system. Labor costs can add **$1,000 $3,000 ** to the total expense.

### **Conclusion**

The **Mercedes-Benz 642-070-15-87-87 injector** is a high-quality, reliable component that ensures optimal engine performance when properly installed. Its OEM status guarantees compatibility, durability, and peace of mind, making it the best choice for owners who prioritize long-term reliability and vehicle value.

However, the **high cost, long lead times, and potential availability issues** make it a less practical option for budget-conscious buyers or those dealing with urgent repairs. If the financial burden is prohibitive, **high-quality aftermarket alternatives** (e.g., Bosch, Delphi, or Stanadyne injectors) may offer a cost-effective compromise while still maintaining performance.

For most owners, **purchasing from an authorized Mercedes-Benz dealer or a trusted OEM supplier** is the safest route, despite the higher expense. If the injector is failing due to age or wear, it may also be worth considering **engine remanufacturing or a full fuel system overhaul** as a more economical solution in the long run.

### **Recommendation:**

- **If budget is not a concern and reliability is the priority**, proceed with the **OEM Mercedes-Benz 642-070-15-87-87 injector** from an authorized source.

- **If cost is a major factor**, research **high-end aftermarket injectors** (e.g., Bosch 0 440 222 002 or equivalent) and consult a Mercedes-Benz specialist to ensure compatibility.

- **For older or high-mileage vehicles**, consider **preventive maintenance** (fuel system cleaning, injector testing) to extend the life of existing injectors before replacement.

- **Always verify the seller s legitimacy** to avoid counterfeit parts, and factor in **labor costs** when budgeting for the repair.

Ultimately, the decision depends on your **financial situation, urgency, and long-term goals** for the vehicle. For most Mercedes-Benz owners, the OEM injector remains the **best choice for performance and longevity**, despite the higher cost.
