Review REIN Crankcase Breather Hose Bmw 3.0l L6 Engine Emission Ma fits C230 135I 2011–2013

The **Rein SX-C7EN Crankcase Breather Hose** is a meticulously engineered, high-performance replacement part specifically designed to restore optimal functionality to the emission control system of the **2011 2013 BMW 135i (N55) with the 3.0L L6 TwinPower Turbo engine**. Engineered with precision and built to exacting standards, this hose is crafted from **high-grade, heat-resistant silicone elastomer**, ensuring exceptional durability, resistance to oil and fuel vapors, and long-term reliability under the demanding conditions of a turbocharged engine. Unlike generic aftermarket alternatives, the SX-C7EN is **OEM-compatible**, meaning it matches the original equipment specifications in both dimensions and performance, eliminating the risk of leaks, clogs, or improper sealing that can compromise engine efficiency and emissions compliance. Its **reinforced construction** prevents kinking, cracking, or degradation from exposure to extreme temperatures, vacuum fluctuations, or the corrosive effects of engine blow-by gases, which are particularly aggressive in high-performance or turbocharged applications. The hose features a **smooth, flexible interior** to facilitate unrestricted airflow while maintaining a secure, leak-proof connection to the **PCV (Positive Crankcase Ventilation) system**, the **turbocharger wastegate**, and the **intake manifold**, all critical components in maintaining proper crankcase pressure and reducing harmful emissions. Whether you're addressing a failing OEM part, upgrading for enhanced reliability, or ensuring compliance with emissions regulations, the Rein SX-C7EN delivers a **direct-fit, no-compromise solution** that restores the integrity of your BMW s emission system with ease. Its **universal fit** for the specified model range makes it an ideal choice for mechanics and enthusiasts alike, offering peace of mind with every installation.

### **Pros and Cons of buying a Rein SX-C7EN Crankcase Breather Hose for a 2011 2013 BMW 135i (3.0L L6 Engine)**

#### **Pros:**

1. **Compatibility and Fitment** The Rein SX-C7EN is specifically designed for the 2011 2013 BMW 335i (N55 engine), ensuring a proper fit without modifications. It replaces the OEM crankcase breather hose, which can degrade over time, leading to leaks or clogging.

2. **Improved Emissions Control** The N55 engine relies on a balanced crankcase ventilation system to maintain proper pressure and reduce blow-by gases. A failing or clogged breather hose can lead to increased emissions, reduced engine efficiency, or even an illuminated check engine light (due to PCV system malfunctions).

3. **Durability and Material Quality** Rein hoses are typically made from high-quality rubber or silicone compounds that resist cracking, oil degradation, and environmental damage better than some OEM alternatives. This can extend the lifespan of the component compared to a worn-out OEM part.

4. **Ease of Installation** The hose is a direct replacement, meaning it should install similarly to the OEM part. Most mechanics or DIYers with basic tools can replace it in under an hour, especially if the engine bay is already accessed for other work.

5. **Cost-Effective Solution** Compared to replacing the entire PCV system or dealing with long-term engine issues caused by a failing breather hose, this is a relatively inexpensive fix. It prevents more costly problems down the line, such as carbon buildup in intake valves or increased oil consumption.

6. **Support for Turbocharged Engines** The N55 s turbocharging system relies on proper crankcase pressure management. A failing breather hose can disrupt this balance, potentially affecting turbo performance or causing oil leaks at seals.

7. **Brand Reputation** Rein is a well-known aftermarket brand with a history of producing reliable automotive hoses and filters. Their products are often backed by warranties, providing some peace of mind against early failure.

#### **Cons:**

1. **Potential Quality Variability** While Rein is a reputable brand, aftermarket parts can still vary in quality depending on the specific batch or supplier. Some users report that certain hoses may not last as long as OEM parts if exposed to extreme heat or oil contamination.

2. **Limited Longevity Compared to OEM (in Some Cases)** OEM hoses on the N55 are generally durable, and some drivers report that Rein hoses may wear out faster if the engine bay is particularly hot or if the vehicle is driven aggressively. However, this is not universal many users find Rein hoses last as long or longer than OEM.

3. **Installation Challenges for DIYers** While the hose itself is straightforward, some users may struggle with securing it properly if they lack experience with engine bay work. Improper sealing can lead to leaks or reoccurring issues.

4. **Price Premium Over OEM** Rein hoses are typically more expensive than a generic OEM replacement part. However, the cost difference is often justified by the improved durability and compatibility.

5. **Compatibility with Modifications** If the vehicle has been modified (e.g., forced induction, exhaust tuning), the crankcase breather system may need adjustments to maintain proper pressure. While the Rein SX-C7EN is a good baseline, additional tuning or upgrades (like a high-flow PCV valve) may be necessary for heavily modified engines.

6. **Potential for Counterfeit Products** As with many aftermarket parts, there is a risk of purchasing a counterfeit Rein hose, especially from untrusted sellers. Always buy from authorized dealers or reputable online retailers to avoid this issue.

### **Ending Conclusion:**

The **Rein SX-C7EN crankcase breather hose is a strong, reliable choice** for the 2011 2013 BMW 335i (N55 engine), offering significant benefits in terms of emissions control, durability, and ease of installation. It addresses common issues with OEM hoses, such as cracking or clogging, while providing a cost-effective solution to prevent more serious engine problems.

**For most drivers**, this hose will perform well and extend the life of the PCV system without requiring frequent replacements. However, if the vehicle is subjected to extreme conditions (e.g., high heat, heavy oil contamination, or aggressive driving), it s wise to monitor its condition and consider upgrading to a higher-end silicone hose if needed.

---

### **Recommendation:**

- **Buy the Rein SX-C7EN** if you re experiencing symptoms of a failing crankcase breather hose (e.g., check engine light for PCV-related codes, oil leaks at the breather, or increased emissions).

- **Pair it with a high-quality PCV valve** (such as the Rein SX-C7EV) for optimal performance, as the valve works in tandem with the breather hose.

- **Install it promptly** if you notice any signs of wear in the OEM hose, as neglecting this can lead to carbon buildup, reduced engine efficiency, or turbocharger issues.

- **Source from a trusted seller** to avoid counterfeit products and ensure you get the genuine Rein part.

- **Consider a silicone alternative** (e.g., Rein SX-C7ES) if you drive in extreme heat or want maximum longevity, though the SX-C7EN is a solid choice for most applications.

**Final Verdict:** The Rein SX-C7EN is a **highly recommended upgrade** for the N55 engine, balancing cost, quality, and performance effectively. It s a straightforward fix that can prevent more expensive repairs down the road.
