The set includes **high-quality, heat-treated steel bolts** with washers and locknuts, providing a secure, vibration-resistant connection that prevents leaks and ensures consistent performance over time. Beyond its performance benefits, this clamp set also offers a subtle yet noticeable aesthetic upgrade, with a sleek, modern look that complements the classic lines of the Electra Glide. Whether you're chasing better throttle response, improving fuel efficiency, or simply refining the engine s character, the **MN/CBJ6 Intake Clamp Set** delivers a measurable upgrade without compromising the timeless charm of your Harley. Perfect for both street cruisers and occasional highway adventurers, this component is a must-have for any owner seeking to unlock the full potential of their Big Twin powerplant.

Buying the **Harddrive MN/CBJ6 Intake Clamp Set** for a 1970 1978 Harley-Davidson FLH Electra Glide involves several considerations. Below is a detailed breakdown of the pros and cons, followed by a conclusion and recommendation.

---

### **Pros of the Harddrive MN/CBJ6 Intake Clamp Set**

1. **OEM Replacement Quality** The Harddrive brand is known for producing high-quality aftermarket parts that closely match or exceed OEM specifications. These clamps are designed to replicate the original function and fit of the intake manifold clamps found on early Electra Glides.

2. **Durability and Reliability** The clamps are made from sturdy materials, often stainless steel or heavy-duty metal, which helps prevent corrosion and wear over time. This is particularly important for older Harley-Davidson engines that may be exposed to moisture or road salt.

3. **Easy Installation** The design of these clamps is straightforward, requiring minimal tools and time to install. They typically feature a simple bolt-on or clamp mechanism, making them accessible even for those with limited mechanical experience.

4. **Compatibility with Modifications** If you ve made modifications to your intake manifold (such as installing a performance air cleaner or aftermarket intake), these clamps will securely hold everything in place without slipping or loosening.

5. **Prevents Leaks** A common issue with aging intake manifolds is leaking gaskets or loose clamps, which can lead to vacuum leaks or oil contamination. Harddrive clamps provide a tight, consistent seal, reducing the risk of such problems.

6. **Cost-Effective Upgrade** Compared to full intake manifold replacements or custom fabrication, these clamps are relatively inexpensive. They offer a simple yet effective solution to a potential failure point without requiring major work.

7. **Maintenance-Friendly** If you need to service your intake manifold (e.g., replacing gaskets or cleaning carbon buildup), these clamps allow for easy disassembly and reassembly without damaging the manifold.

### **Cons of the Harddrive MN/CBJ6 Intake Clamp Set**

1. **Potential for Over-Tightening** Some users report that these clamps can be overly tight if not installed correctly, risking damage to the intake manifold or warping the metal over time. It s important to follow the manufacturer s torque specifications to avoid this.

2. **Limited Customization** Unlike some aftermarket alternatives, these clamps are designed for a specific application (MN/CBJ6 intake manifolds). If you ve made extensive modifications to your intake setup, you may need additional adapters or custom solutions.

3. **Quality Variability** While Harddrive is generally reliable, there have been occasional reports of subpar batches or manufacturing inconsistencies. Always inspect the clamps upon arrival for defects (e.g., cracks, rust, or improper threading).

4. **Not a Permanent Fix for Worn Manifolds** If your intake manifold itself is cracked, corroded, or otherwise damaged, replacing the clamps will not address the root issue. In such cases, a full manifold replacement may be necessary.

5. **May Require Additional Sealants** Some users find that these clamps work best when combined with a high-temperature gasket maker or sealant to ensure a perfect fit, especially if the manifold or clamps are slightly worn.

6. **Limited Availability of Replacement Parts** If you encounter issues down the line (e.g., a clamp breaking), finding exact replacements may be more difficult than sourcing OEM parts, though Harddrive typically has good availability.

7. **Installation Knowledge Required** While the installation is simple, improper handling (e.g., cross-threading or overtightening) can lead to problems. Those unfamiliar with Harley-Davidson engines may need to consult a mechanic or detailed instructions.

### **Conclusion**

The **Harddrive MN/CBJ6 Intake Clamp Set** is a practical and cost-effective solution for addressing common intake manifold clamp issues on a 1970 1978 FLH Electra Glide. It offers OEM-quality durability, ease of installation, and prevents leaks that could affect engine performance. However, it is not a universal fix it requires proper installation techniques and may need to be paired with additional sealants or gaskets for optimal results. If your intake manifold is severely worn or damaged, these clamps alone will not suffice, and a more comprehensive repair may be needed.

### **Recommendation**

If your primary concern is **loose or failing intake clamps** and the rest of your intake manifold is in good condition, the **Harddrive MN/CBJ6 Intake Clamp Set** is a solid choice. It strikes a balance between affordability, reliability, and ease of use. Before purchasing, ensure the clamps are compatible with your specific manifold configuration (some early Electra Glides may have slight variations).

For best results:

- **Inspect your current clamps** to confirm they are the correct type (MN/CBJ6).

- **Use a torque wrench** to avoid overtightening.

- **Apply a high-temperature gasket maker** if the manifold or clamps show signs of wear.

- **Consider a full intake manifold inspection** if you notice leaks, cracks, or excessive carbon buildup.

If you re unsure about installation or suspect deeper issues with your intake system, consult a Harley-Davidson specialist or a trusted mechanic to avoid unnecessary repairs. For most users, this clamp set will provide a reliable, long-term solution without major drawbacks.
