Review EDDIE MOTORSPORTS Chevy Ls Coil Relocation Bracket Kit

The **Eddie s LS Coil Relocation Bracket Kit (MS109-11MB)** is a meticulously engineered solution designed to elevate the performance and reliability of your Chevrolet LS-based engine by optimizing coil pack placement and routing. This high-quality kit is specifically tailored for applications requiring a more streamlined, efficient, and durable coil relocation system, making it an ideal choice for enthusiasts and professional mechanics working on LS engines in a wide range of vehicles, from stock builds to high-performance street machines and even competition applications. Crafted from heavy-duty, corrosion-resistant materials, the bracket system ensures long-lasting durability while maintaining a clean, professional appearance under the hood. The kit features precision-machined brackets that securely mount the coil packs away from the engine bay s hottest zones, reducing the risk of heat damage and improving overall reliability especially in high-output or forced-induction applications where coil longevity is critical. With a focus on ease of installation, the MS109-11MB kit includes all necessary hardware, including robust mounting studs, washers, and locking nuts, ensuring a tight and vibration-free fit. Whether you're upgrading an LS1, LS2, LS3, or LS7 engine, this coil relocation kit helps declutter the engine bay, simplifies wiring management, and enhances airflow, contributing to better cooling and a more organized under-hood environment. Ideal for both aftermarket and OEM applications, this kit is a must-have for anyone looking to protect their coils, improve engine bay aesthetics, and future-proof their build against the stresses of high-performance driving.

### **Pros and Cons of buying a Eddie MS109-11MB Chevy LS Coil Relocation Kit**

#### **Pros:**

The Eddie MS109-11MB coil relocation kit is designed specifically for LS-based engines (Gen III/IV) and offers several advantages for performance and drivability:

1. **Improved Engine Performance** Coil relocation moves the ignition coils away from the exhaust headers, reducing heat exposure. This helps prevent misfires caused by excessive heat, leading to more consistent spark delivery and better combustion efficiency.

2. **Enhanced Reliability** By reducing heat-induced coil failure, the kit can extend the lifespan of ignition components, reducing the risk of sudden misfires or complete coil burnout, especially in high-performance or turbocharged applications.

3. **Better Turbocharged/Supercharged Compatibility** For forced-induction builds, keeping coils away from exhaust manifolds prevents heat soak, which can degrade spark timing and fuel efficiency. This kit is particularly useful for LS engines running turbos or superchargers.

4. **Easier Installation** The kit is designed for straightforward installation, often requiring minimal modifications to existing wiring or mounting points. Eddie s kits are known for their compatibility with aftermarket LS engine builds.

5. **Cost-Effective Upgrade** Compared to full coil packs or custom wiring solutions, this is a relatively affordable way to address coil heat issues without major engine modifications.

6. **Retains Stock Functionality** Unlike some aftermarket coil packs, this kit maintains the stock LS coil design while simply relocating them, making it a more conservative upgrade option.

7. **Supports High-Performance Tuning** By ensuring stable ignition performance, the kit allows for better tuning flexibility, especially when paired with aggressive camshafts, high-flow fuel injectors, or forced induction.

#### **Cons:** While the Eddie MS109-11MB kit has many benefits, there are some potential drawbacks to consider:

1. **Limited Stock Compatibility** This kit is **not universal** and is specifically designed for **11MB (2006 2013) LS engines** (e.g., LS3, LS9, LS7, LS2 with certain modifications). Owners of older (pre-2006) or newer (post-2013) LS engines may need a different kit or custom solution.

2. **Wiring Modifications Required** Relocating coils often necessitates rerouting wiring harnesses, which may involve cutting, splicing, or using additional connectors. This can add complexity if the owner is not experienced with electrical work.

3. **Potential for Misalignment Issues** If not installed precisely, the new coil positions might interfere with engine components (e.g., intake manifold, throttle body, or exhaust headers). Careful measurement and alignment are required.

4. **No Direct Spark Plug Access** Unlike coil packs, this kit keeps the original LS coil design, meaning spark plugs remain in their stock positions. This may not be ideal for builds requiring easier spark plug access or custom ignition timing solutions.

5. **Not a Full Coil Pack Replacement** For extreme performance applications (e.g., high RPM drag racing or aggressive turbo builds), a full coil pack (like those from MSD or Coil Craft) may offer better spark consistency and tuning flexibility.

6. **Potential for Grounding Issues** Relocating coils may require additional grounding points or shielding to prevent electrical interference, especially in high-voltage environments.

7. **Aftermarket Dependency** Some users report that certain aftermarket components (e.g., headers, turbochargers) may not clear the relocated coils, requiring further modifications.

### **Ending Conclusion**

The **Eddie MS109-11MB LS Coil Relocation Kit** is a **practical and effective solution** for LS engine owners (especially 11MB models) looking to eliminate heat-induced misfires, particularly in turbocharged or high-performance applications. It strikes a balance between simplicity and performance improvement, offering a **cost-effective alternative to full coil pack upgrades** while maintaining stock ignition reliability.

However, it is **not a one-size-fits-all solution** it requires careful installation, may necessitate wiring adjustments, and is **engine-specific**. If you re running a **stock or mildly modified LS engine**, this kit can be a **solid upgrade**. For **extreme builds (e.g., high-RPM drag racing, aggressive turbo setups, or custom ignition tuning)**, a **full coil pack system** might be more beneficial in the long run.

---

### **Recommendation**

**Buy the Eddie MS109-11MB Coil Relocation Kit if:**

- You have an **11MB LS engine (2006 2013)** and experience **heat-related misfires**.

- You re running **turbocharging, supercharging, or aggressive camshafts** and need to protect your coils.

- You want a **simple, reliable upgrade** without a full coil pack swap.

- You re comfortable with **basic wiring modifications** and precise installation.

**Consider alternatives if:**

- You have a **non-11MB LS engine** (e.g., pre-2006 or post-2013), requiring a different kit.

- You need **easier spark plug access** or **custom ignition timing** (a coil pack may be better).

- You re building a **high-end race engine** where **maximum reliability and tuning flexibility** are critical.

**Final Verdict:** For most **11MB LS engine builds** where heat is a concern, this kit is a **smart, budget-friendly choice** that delivers noticeable improvements in drivability and longevity. Pair it with a **high-quality ignition system (e.g., MSD ignition box for turbo builds)** for optimal results.
