Review RAREELECTRICAL Breather Hose Bmw Alpina 4.4l Cyl fits 550I 650I 750LI GT 2009–2013

The **RB54170008A1 Breather Hose** is a high-performance, precision-engineered replacement part designed specifically for BMW Alpina models, including the **550i, 650i, and 750Li (GT) from 2009 to 2013**, all equipped with the **4.4L V8 engine (OEM part number 11157575640)**. Crafted from durable, high-quality **reinforced rubber and synthetic materials**, this breather hose is engineered to withstand the demanding conditions of high-performance driving while ensuring optimal engine breathing efficiency. The hose features a **tight, secure fit** with precision-molded connectors that align perfectly with the engine bay s intake and exhaust breather system, preventing leaks, vacuum loss, or contamination from oil, coolant, or debris. Its **robust construction** minimizes the risk of cracking or degradation over time, even under extreme temperatures or aggressive driving conditions, which is particularly important for high-revving Alpina engines that rely on consistent airflow for peak performance. Whether installed in a daily driver, a track-focused machine, or a restored classic, this breather hose guarantees reliable operation, helping maintain proper engine vacuum levels, reduce carbon buildup, and extend the lifespan of critical components like the **PCV system, intake manifold, and turbocharger** (where applicable). Built to meet or exceed OEM specifications, it provides a seamless upgrade that enhances both performance and longevity, making it an essential component for any BMW Alpina owner seeking to preserve their vehicle s factory integrity or upgrade to aftermarket modifications.

### **Pros and Cons of buying a RB54170008A1 Breather Hose (2009 2013 BMW Alpina 550i/650i/750Li GT 4.4L, Part #11157575640)**

#### **Pros:**

1. **OEM Quality and Fit** This is a genuine BMW Alpina part, meaning it is designed specifically for your vehicle s engine bay layout, ensuring a proper fit without modifications. OEM parts are built to the same standards as factory components, reducing the risk of premature failure.

2. **Reliability and Durability** BMW s engineering ensures that this breather hose is made from high-quality materials resistant to oil, coolant, and heat. A well-made breather system prevents carbon buildup in the intake, reducing engine wear over time.

3. **Prevents Engine Contamination** The breather hose helps manage crankcase pressure by routing fumes away from the engine bay, preventing oil and debris from entering the intake system. This reduces the risk of carbon deposits on intake valves and pistons, which can lead to performance loss and increased emissions.

4. **Compatibility with Turbocharged Engines** The 4.4L N63 V8 in your Alpina models is turbocharged, and a properly functioning breather system is critical for maintaining boost pressure and preventing turbo spool issues caused by restricted airflow.

5. **Ease of Installation** As an aftermarket or OEM replacement, this part is straightforward to install, typically requiring only basic tools. Many mechanics and DIYers report that the hose connects easily to the existing breather system without requiring additional modifications.

6. **Long-Term Cost Savings** While the upfront cost may be higher than some aftermarket alternatives, a high-quality breather hose reduces the likelihood of costly engine damage (e.g., carbon buildup, turbo failure) in the long run.

7. **Warranty Coverage** If purchased from an authorized BMW dealer or a reputable supplier, this part may come with a warranty, providing peace of mind against defects.

---

#### **Cons:**

1. **Higher Upfront Cost** Compared to generic aftermarket breather hoses, an OEM or high-quality replacement will be more expensive. For example, this specific part may cost significantly more than a non-branded alternative from a big-box auto store.

2. **Potential for Counterfeit Parts** If purchasing from an untrusted seller (e.g., eBay, Amazon, or unlicensed dealers), there is a risk of receiving a counterfeit or low-quality knockoff. Always verify the seller s authenticity and part numbers.

3. **Limited Availability Outside BMW Dealers** While this part is widely available, it may not be stocked at every local auto parts store. You may need to order it online, which could introduce delays or require shipping costs.

4. **Mixed Reviews on Aftermarket Alternatives** Some owners report that certain aftermarket breather hoses (even from reputable brands) fail prematurely or leak, leading to frustration. If cost is a concern, thorough research into alternative brands (e.g., Mann, Bosch, or ACDelco) is advisable.

5. **Installation Complexity for Non-Mechanics** While the hose itself is simple to replace, some owners may find that the surrounding area (e.g., engine bay wiring, other hoses) requires careful handling to avoid damage. If unsure, professional installation is recommended.

6. **Environmental Concerns** Like all rubber hoses, this part will eventually degrade over time due to heat, oil, and UV exposure. While not a con of the part itself, it underscores the need for regular inspection and replacement as part of routine maintenance.

### **Conclusion:**

The **RB54170008A1 breather hose (11157575640)** is a **highly recommended choice** for owners of the 2009 2013 BMW Alpina 550i/650i/750Li GT with the 4.4L N63 engine. Its **OEM quality, reliability, and critical role in preventing engine contamination** make it a worthwhile investment for long-term performance and protection. However, the **higher cost and potential for counterfeit parts** require careful consideration of where and how you purchase it.

If budget is a concern, **thoroughly research aftermarket alternatives** (e.g., Mann Filter, Bosch, or ACDelco) and read owner reviews to ensure compatibility. Always prioritize **authentic parts from trusted suppliers** (BMW dealers, specialty BMW shops, or reputable online retailers like RockAuto, Amazon, or eBay with verified sellers).

---

### **Final Recommendation:**

- **Best Choice:** Purchase the **OEM RB54170008A1 (11157575640)** from an **authorized BMW dealer** or a **trusted BMW parts supplier** (e.g., RockAuto, BMW Parts Online). This ensures authenticity and warranty coverage.

- **Budget Alternative:** If cost is a factor, consider **high-quality aftermarket brands** (e.g., Mann Filter 11157575640 equivalent, Bosch, or ACDelco) from a well-reviewed seller. Verify compatibility with your exact model year and engine variant.

- **Installation:** If comfortable with basic mechanical work, replace the hose yourself. If not, have a **BMW specialist or reputable mechanic** perform the installation to avoid mistakes.

- **Maintenance Tip:** Inspect the breather system **every 30,000 50,000 miles** for cracks, leaks, or clogs, as a failing hose can lead to serious engine issues.

**Verdict:** This is a **critical, high-value part** for your Alpina s performance and longevity. Do not skimp on quality prioritize authenticity to avoid future problems.
