Review LENKDOU Cnc Air Cleaner Engine Breather Oil Collector Kit Harley Custom Indian Bmw

The **Lenkdou MP09-001-0025BL1 CNC Engine Breather & Oil Collector Kit** is a meticulously engineered aftermarket solution designed to enhance the performance, reliability, and longevity of high-performance engines in Harley-Davidson and BMW motorcycles. This precision-machined kit replaces the stock air cleaner and engine breather system with a high-flow, dual-stage filtration setup that significantly reduces oil vapor emissions, minimizes blow-by, and prevents carbon buildup in critical engine components. Crafted from durable, lightweight aluminum via CNC machining, the kit features a sleek, aerodynamic design that integrates seamlessly with modern engine bay aesthetics while maximizing airflow efficiency. The system includes a high-capacity oil collector bowl that effectively traps and recirculates engine oil vapors back into the crankcase, reducing oil consumption and preventing costly internal damage from carbon deposits. Paired with a high-quality, replaceable foam or cotton filter element, this kit ensures optimal air intake while maintaining peak engine cleanliness. Ideal for both street and track applications, the Lenkdou MP09-001-0025BL1 is a game-changer for riders seeking improved throttle response, reduced emissions, and extended engine life without compromising on performance or style. Perfect for high-mileage bikes or those subjected to aggressive riding conditions, this kit is a must-have upgrade for enthusiasts who demand the best in engine protection and efficiency.

### **Pros and Cons of buying a Lenkdou MP09-001-0025BL1 CNC Air Cleaner/Engine Breather/Oil Collector Kit for Harley-Davidson and BMW**

#### **Pros**

1. **Improved Engine Breathing and Performance**

The kit replaces stock air cleaners and breather systems with CNC-machined components designed for better airflow. This can enhance engine efficiency, reduce backpressure, and improve throttle response, especially in high-performance or modified engines.

2. **Reduced Oil Foaming and Contamination**

The oil collector system helps prevent oil from entering the air intake, reducing oil foaming in the crankcase. This is particularly beneficial for engines prone to oil dilution (e.g., BMW S55/S65) or those running high-performance setups with aggressive breathing.

3. **Precision Engineering and Durability**

Lenkdou markets this as a CNC-machined kit, suggesting high-quality manufacturing with tight tolerances. The materials appear to be robust, which could extend the lifespan of the components compared to aftermarket alternatives with lower build quality.

4. **Compatibility with Harley-Davidson and BMW Engines**

The kit is explicitly designed for Harley-Davidson (likely Big Twin or V2 engines) and BMW (possibly N54, S55, or S65 applications). This means it should fit without major modifications, though exact compatibility should be verified with the manufacturer or a trusted mechanic.

5. **Potential for Better Cooling and Oil Return**

Some breather/oil collector systems improve oil return to the crankcase, reducing heat buildup and ensuring smoother engine operation, especially under heavy loads or in high-temperature environments.

6. **Aesthetic and Customization Appeal**

For enthusiasts who prioritize a clean, modern look, the CNC-machined components may offer a sleeker alternative to stock or generic aftermarket parts.

7. **Potential for Reduced Oil Consumption**

By minimizing oil loss through the breather system, the kit could help reduce oil consumption in engines prone to burning oil, though results vary by application.

---

#### **Cons**

1. **Cost**

High-quality CNC-machined kits are typically more expensive than standard aftermarket replacements. The price may be a significant investment, especially if the owner is not pursuing high-performance tuning.

2. **Installation Complexity**

Depending on the engine and existing setup, installation may require disassembly of parts of the air intake, breather system, or oil pan. This could be time-consuming and may necessitate professional assistance, adding to labor costs.

3. **Limited Real-World Performance Gains**

While the kit promises improved airflow and oil management, the actual performance benefits depend on the engine s condition, tuning, and other modifications. In some cases, the gains may be marginal, especially on stock or lightly modified engines.

4. **Potential for Voiding Warranty**

If the vehicle is under warranty, installing aftermarket breather or air cleaner systems could void coverage, particularly if the manufacturer considers it a "non-OEM" modification.

5. **Compatibility Risks**

While Lenkdou claims compatibility with Harley-Davidson and BMW engines, there is always a risk of misalignment or improper fitment. Users should double-check specifications or consult a specialist before purchasing.

6. **Maintenance Requirements**

CNC-machined parts may require periodic inspection for wear or damage, especially in high-stress applications. Oil and air filters may need more frequent replacement to ensure optimal performance.

7. **Market Availability and Support**

If the kit is relatively new or niche, finding replacement parts or technical support could be challenging compared to more established brands.

### **Ending Conclusion**

The **Lenkdou MP09-001-0025BL1 CNC Air Cleaner/Engine Breather/Oil Collector Kit** is a well-engineered solution for enthusiasts seeking improved airflow, reduced oil contamination, and precision-machined components for Harley-Davidson and BMW engines. It is particularly valuable for high-performance or modified setups where stock breather systems are inadequate. However, the cost, installation complexity, and potential lack of dramatic real-world gains on stock engines must be carefully considered.

For **stock or lightly modified engines**, the benefits may not justify the expense, and simpler aftermarket breather systems could suffice. For **high-performance builds, oil management issues, or enthusiasts prioritizing precision engineering**, this kit offers a strong alternative to generic replacements.

### **Recommendation**

- **Purchase if:**

- You are running a modified or high-performance engine (e.g., turbocharged, supercharged, or heavily tuned).

- Your engine suffers from oil foaming, excessive oil consumption, or poor breathing (e.g., BMW N54/S55, Harley-Davidson V2).

- You value CNC-machined components and are willing to invest in a high-quality, long-lasting solution.

- You have mechanical experience or are prepared to pay for professional installation.

- **Avoid if:**

- Your engine is stock or minimally modified, and you are unsure of the performance gains.

- You are on a tight budget, as cheaper alternatives may offer similar benefits.

- You are uncomfortable with installation complexity or potential warranty risks.

- You cannot verify exact compatibility with your specific engine model.

**Final Suggestion:** Before purchasing, consult with a trusted mechanic or performance specialist to confirm fitment and expected benefits. Additionally, review user feedback or forums (e.g., Harley-Davidson or BMW tuning communities) for real-world experiences with this kit.
