The **GB Remanufactured 842-12116 Port Fuel Injector** is a high-performance, precision-engineered component designed to restore optimal fuel delivery and engine efficiency in modern gasoline-powered vehicles. This injector is part of General Motors (GM) original equipment lineup, specifically tailored for applications requiring a **port-style fuel injector** a design that injects fuel directly into the intake port rather than the combustion chamber, ensuring a cleaner burn and improved throttle response. Built to meet or exceed OEM specifications, this remanufactured unit undergoes a rigorous multi-step restoration process that includes thorough disassembly, ultrasonic cleaning, and meticulous inspection of internal components such as the solenoid, valve needle, and O-ring seals. Each injector is then reassembled with high-quality, GM-approved materials, including a **ceramic-coated valve needle** for enhanced durability and consistent spray pattern integrity, while the solenoid is tested for precise electrical performance to ensure reliable activation under varying engine conditions. The **port design** of this injector allows for a more gradual fuel-air mixture, reducing the risk of carbon buildup and promoting smoother engine operation, particularly in high-performance or turbocharged applications. Whether replacing a failed OEM injector or upgrading an older vehicle to modern standards, the **842-12116** delivers dependable performance, compatibility with GM s fuel injection systems, and the confidence of a professionally remanufactured part backed by GB s reputation for quality and reliability. Ideal for technicians and DIY enthusiasts alike, this injector is a cost-effective solution for restoring engine performance without sacrificing precision or longevity.
### **Pros and Cons of Buying a Genuine BMW Remanufactured Fuel Injector (Part Number: 842-12116 / 84212116)**
#### **Pros:**1. **Reliability and Performance** Remanufactured injectors from BMW s authorized service providers (like Genuine BMW Remanufacturing) undergo rigorous testing and restoration to meet OEM specifications. This ensures they function as closely as possible to new injectors, improving fuel efficiency, engine performance, and emissions compliance.
2. **Cost-Effective Alternative to New** Remanufactured injectors are significantly cheaper than brand-new OEM injectors, making them a practical choice for budget-conscious owners who still want quality.
3. **Warranty Coverage** Genuine BMW remanufactured parts often come with a warranty (typically 12 24 months), providing peace of mind against premature failure. This is often longer than what aftermarket injectors may offer.
4. **Compatibility and Fitment** Since these are OEM parts, they are designed specifically for BMW engines, ensuring proper fitment, calibration, and compatibility with the vehicle s fuel management system.
5. **Environmental Benefit** Remanufacturing reduces waste by reusing existing components rather than producing entirely new ones, aligning with sustainability efforts.
6. **Access to Original BMW Specifications** The remanufacturing process adheres to BMW s engineering standards, meaning the injector will meet the same performance and durability benchmarks as a new part.
7. **Support from BMW Dealerships** Purchasing from an authorized BMW service center ensures technical support, proper diagnostics, and compatibility with BMW s vehicle systems.

#### **Cons:**1. **Higher Upfront Cost Than Aftermarket** While cheaper than new OEM injectors, remanufactured parts are still more expensive than generic aftermarket alternatives, which may appeal to cost-sensitive buyers.
2. **Limited Availability** Genuine BMW remanufactured parts may not be as widely stocked as aftermarket options, potentially requiring longer wait times or special ordering.
3. **Potential for Mixed Quality** If purchased from unauthorized or counterfeit sources (posing as "Genuine BMW"), the quality may be compromised. Always verify the seller s authenticity (e.g., BMW dealership, authorized remanufacturer).
4. **Installation Complexity** Fuel injectors require precise installation, including recalibration of the engine control unit (ECU). Improper installation can lead to performance issues or even damage to the fuel system.
5. **Warranty Limitations** Some warranties may exclude labor costs or only cover defects under specific conditions (e.g., improper installation). Always review warranty terms carefully.
6. **Depreciation Risk** Like all used or remanufactured parts, the value of a remanufactured injector diminishes over time, especially if the vehicle is older.
7. **Compatibility with Modified Engines** If the vehicle has been heavily modified (e.g., turbocharged, tuned), the remanufactured injector may not be optimized for the altered fuel delivery requirements, potentially leading to performance mismatches.

### **Conclusion:**Genuine BMW remanufactured fuel injectors (842-12116) strike a balance between quality, cost, and reliability, making them an excellent choice for owners seeking an OEM-level solution without the premium price of new parts. They are particularly well-suited for:
- **Routine maintenance** (e.g., replacing worn injectors in a high-mileage vehicle).
- **Restoring performance** in a well-maintained BMW engine.
- **Ensuring emissions compliance** (especially in regions with strict regulations).
- **Owners who prioritize long-term reliability** over short-term savings.
However, they may not be the best option for:- **Budget-conscious buyers** who can find equally reliable aftermarket injectors at a fraction of the cost.
- **Vehicles with extensive modifications** that require specialized injectors.
- **Emergency repairs** where aftermarket parts are immediately available.

### **Recommendation:**If you are replacing a faulty or worn fuel injector in your BMW and prioritize **reliability, warranty coverage, and OEM compatibility**, purchasing a **Genuine BMW remanufactured injector (842-12116)** from an **authorized BMW service center or dealership** is the best choice. Ensure the seller is verified to avoid counterfeit parts, and have the installation performed by a qualified technician to guarantee proper calibration and performance.
If cost is a major concern and the vehicle is not heavily modified, **high-quality aftermarket injectors from reputable brands** (e.g., Delphi, Denso, or Stanadyne) may offer comparable performance at a lower price, provided they are properly matched to your engine s specifications.
For most BMW owners, the remanufactured option provides the best combination of **cost savings, quality, and peace of mind**. Always cross-reference the part number with your vehicle s specifications to confirm compatibility.
