Review BMW G26 Rear Left Right Side Engine Mount Bracket Pair Oem fits I4 2022–2026

The **BMW 8742123 (2022 2026 i4 G26 Rear Left/Right Engine Mount Bracket)** is a precision-engineered suspension component designed exclusively for the latest generation of BMW s electrified i4 platform, specifically the G26 model series. This high-performance bracket serves as a critical structural link between the powertrain and the vehicle s chassis, ensuring optimal alignment, vibration damping, and load distribution while maintaining the i4 s signature driving dynamics. Crafted from durable, high-grade materials likely reinforced polymer or composite alloys this bracket is engineered to withstand the unique stresses of an electric powertrain, which lacks the traditional engine s natural vibration dampening. Its sleek, aerodynamic design integrates seamlessly with the i4 s underbody architecture, minimizing aerodynamic drag while maximizing rigidity to prevent flex under acceleration, braking, or cornering forces. The bracket s precise fitment is tailored to the G26 s rear-wheel-drive electric layout, accommodating the compact yet powerful electric motor s torque delivery system, which demands both stability and responsiveness. Whether installed during original equipment assembly or as part of a performance or maintenance upgrade, this component plays a pivotal role in preserving the i4 s handling precision, ride comfort, and long-term structural integrity. Its compatibility with the 2022 2026 model years ensures seamless integration with the latest software and suspension tuning refinements, making it an essential part of BMW s commitment to delivering a refined, high-performance electric driving experience.

Buying a replacement **BMW i4 (G26) rear left/right engine mount bracket (part number 8742123 for model years 2022 2026)** involves weighing several factors to determine whether it s the right choice for your needs.

### **Pros of purchasing a Part**

1. **OEM Quality and Fit** The part is an original BMW component, ensuring a precise fit and compatibility with the G26 platform. This reduces the risk of misalignment or improper installation, which can affect drivability or suspension performance.

2. **Durability and Longevity** BMW s engineering standards typically result in parts that are built to last, especially when compared to aftermarket alternatives that may use cheaper materials. This can extend the lifespan of your engine mounts and reduce long-term maintenance costs.

3. **Warranty Coverage** If purchased from an authorized BMW dealer or a reputable seller, the part may come with a warranty (e.g., 12 24 months), providing peace of mind against premature failure.

4. **Reliability for Performance** The i4 s electric powertrain relies on precise mount alignment to minimize vibrations and ensure optimal energy transfer. A faulty or worn mount can lead to rattling, uneven power delivery, or even damage to the battery or drivetrain components. Replacing it with an OEM part helps maintain system integrity.

5. **Resale Value Protection** Keeping your vehicle in top condition with genuine parts can help preserve its resale value, especially for a relatively new model like the i4.

6. **Ease of Installation (If DIY-Friendly)** While engine mount replacement can be labor-intensive, the OEM part is designed to work seamlessly with BMW s mounting hardware. Some owners may find it easier to install than aftermarket alternatives that require additional modifications.

### **Cons of purchasing a Part**

1. **High Cost** OEM BMW parts are significantly more expensive than aftermarket equivalents. The price for a single rear engine mount bracket (or a pair) can range from **$200 $400 **, depending on the seller and whether taxes/fees are included. This can be a substantial upfront investment, especially if you re on a tight budget.

2. **Longer Wait Times** OEM parts from dealers may take **days or even weeks** to arrive, depending on inventory levels and shipping logistics. Aftermarket options are often available faster.

3. **Labor Costs** Replacing engine mounts typically requires **specialized tools** (e.g., hydraulic press, torque wrench) and **expertise** to ensure proper alignment. If you re not comfortable with mechanical work, labor costs at a BMW dealership or specialist shop can add **$200 $500 ** to the total expense.

4. **Potential Overkill for Minor Issues** If the mount is only slightly worn or the noise/vibration is minor, some owners opt for aftermarket parts or temporary fixes (e.g., vibration dampeners) to save money. An OEM replacement may be unnecessary in such cases.

5. **Limited Customization** Unlike aftermarket parts, OEM mounts do not offer performance upgrades (e.g., stiffer mounts for better handling) or aesthetic modifications. If you re looking to enhance the car s tuning, aftermarket options may be more versatile.

6. **Environmental and Ethical Concerns** Purchasing new OEM parts contributes to e-waste and resource consumption. Some buyers prefer refurbished or remanufactured parts as a more sustainable alternative.

### **Alternatives to Consider**

- **Aftermarket OEM-Compatible Parts** Brands like **Felgen, Meyle, or ACDelco** offer high-quality, OEM-equivalent mounts at a fraction of the cost. These are often just as durable and come with warranties.

- **Refurbished/Remanufactured Parts** Some sellers offer reconditioned BMW mounts that have been inspected, cleaned, and tested. This can be a cost-effective middle ground.

- **DIY vs. Professional Installation** If you have mechanical experience, installing the part yourself can save labor costs. However, improper installation can void warranties or cause further damage.

- **Extended Warranty Coverage** If your i4 is still under BMW s factory warranty (typically **4 years/50,000 miles**), the cost of replacement may be fully or partially covered. Check your warranty terms before purchasing.

### **Conclusion**

Buying the **OEM BMW 8742123 rear engine mount bracket (2022 2026 i4 G26)** is the **best choice for reliability, longevity, and peace of mind**, especially if you prioritize original equipment quality and warranty protection. It is ideal for:

- Owners who want to **maintain factory specifications** and avoid potential drivability issues.

- Those who are **willing to invest in long-term durability** and resale value.

- Situations where **vibration, rattling, or alignment issues** are severe enough to justify the cost.

However, if **budget constraints** or **minor symptoms** are the primary concern, **aftermarket OEM-compatible parts** or **refurbished options** may be more practical. Additionally, always verify whether your **vehicle s warranty** covers the repair before proceeding.

### **Final Recommendation**

- **If you can afford it and need the highest quality:** Purchase the **OEM part from an authorized BMW dealer or a trusted online retailer** (e.g., BMW Parts Online, RockAuto, or a BMW specialty shop). Ensure the part is **genuine and not a counterfeit**.

- **If cost is a concern but quality is still important:** Opt for a **high-quality aftermarket OEM-compatible bracket** (e.g., Meyle or Felgen) and have it installed by a **certified BMW technician** to avoid voiding any remaining warranty.

- **If the issue is minor or you re unsure:** Consult a **BMW specialist** to diagnose whether the mount is truly failing or if another component (e.g., suspension, battery mount) is causing the problem.

For most i4 owners experiencing **rear engine mount wear**, the OEM part is the **safest long-term solution**, but weigh the cost against alternatives to make the best decision for your situation.
