Review ARLEN NESS Mn/cqt1 Billet Sucker And Big Stage Hardware Kit Dj fits 2003–2006

The **Arlen Ness MN/CQT1 Billet Sucker Big Kit** is a meticulously engineered, high-performance upgrade designed specifically for the 2003 2006 Dodge Jeep Grand Cherokee (DJ) models equipped with the **3.6L Pentastar V6** or **3.7L/4.0L HEMI V8** engines, particularly those featuring the **Multi-Displacement Control Technology (MDCT)** or **Cylinder Deactivation (CQT)** systems. This kit is crafted to address the inherent limitations of the factory billet oil pump and suction system, which can lead to oil starvation, reduced engine longevity, and diminished performance under high-stress conditions like aggressive driving, towing, or heavy loads. The **Big Kit** stands out as the most comprehensive solution in Arlen Ness s lineup, combining a **high-flow billet oil pump**, an **enlarged oil filter housing**, an **upgraded oil filter**, and a **reinforced oil pickup tube** to ensure a consistent, high-pressure oil supply to critical engine components, even under extreme demands. Engineered from premium billet aluminum, the oil pump features precision-machined internal components that minimize internal slippage, maximizing oil flow efficiency while maintaining smooth operation. The kit s **oversized filter housing** accommodates larger oil filters, such as those from Mann or WIX, which provide extended service intervals and superior filtration, reducing sludge buildup and prolonging engine health. The **reinforced oil pickup tube** is designed to resist warping and cracking under high temperatures, while its extended length ensures it remains submerged in oil even during aggressive cornering or steep inclines, preventing air from being drawn into the system. Whether you re pushing the limits on the track, hauling heavy payloads, or simply seeking to future-proof your engine against premature wear, the **MN/CQT1 Billet Sucker Big Kit** delivers a robust, all-encompassing solution that restores confidence in your Jeep s power delivery and reliability. Backed by Arlen Ness s reputation for precision engineering and performance-driven innovation, this kit is an essential upgrade for enthusiasts who demand nothing less than peak mechanical efficiency from their 2003 2006 DJ.

### **Pros and Cons of buying a Arlen Ness MN/CQT1 Billet Sucker Big Kit for 2003 2006 Dodge Jeep (DJ) Engines**

#### **Pros**

1. **Performance Gains** The billet sucker kit is designed to improve airflow and scavenging in the engine, which can lead to noticeable power increases, especially in naturally aspirated or mildly modified engines. Many users report better throttle response and mid-range torque.

2. **Durability and Strength** Billet aluminum construction is stronger and more resistant to warping than cast components, reducing the risk of failure under high-performance conditions. The kit is built to handle increased airflow without compromising structural integrity.

3. **Compatibility** The MN/CQT1 designation ensures this kit is specifically engineered for the 5.7L (345 ci) HEMI engines found in 2003 2006 Dodge trucks, Jeeps, and Ram pickups. It integrates well with stock and aftermarket components, including intake manifolds and headers.

4. **Improved Scavenging** The kit s design enhances cylinder scavenging, which helps reduce backpressure and allows for better combustion efficiency. This can translate to smoother operation and reduced pumping losses.

5. **Aftermarket Support** Arlen Ness is a well-respected brand in the performance community, and this kit is widely supported by tuners and performance shops. There are numerous tuning solutions (stock or aftermarket) that can optimize performance when paired with the kit.

6. **Potential for Future Mods** If you plan to add forced induction (turbo or supercharger) later, a billet sucker kit can help mitigate some of the challenges associated with high-flow scenarios, such as valve float or excessive backpressure.

7. **Aesthetic Appeal** The billet construction gives the engine bay a premium, high-performance look, which can be appealing if you value engine cosmetics.

#### **Cons**

1. **Cost** The Arlen Ness MN/CQT1 Billet Sucker Kit is not a budget-friendly upgrade. Prices typically range from **$1,500 to $2,500 **, depending on whether you include additional components (e.g., headers, intake, or tuning). This is a significant investment for a naturally aspirated power gain.

2. **Installation Complexity** Installing the kit requires removing the stock intake manifold, exhaust headers, and possibly the valve cover. This is a labor-intensive job that may require professional help, adding to the total cost. Improper installation can lead to leaks, performance issues, or even engine damage.

3. **Tuning Required** While the kit improves airflow, it can also create tuning challenges. Stock ECUs may not properly map the increased airflow, leading to rough idle, hesitation, or even stalling. You ll need a **custom tune** (from a reputable tuner like Haltech, AEM, or a local shop) to optimize performance and prevent drivability issues.

4. **Limited Power Gains Without Further Mods** The kit alone may only yield **10 20 HP and 10 20 lb-ft of torque** in stock form. For significant power gains, you ll likely need to pair it with other mods (e.g., headers, a high-flow intake, or forced induction), which further increases cost and complexity.

5. **Potential for Increased Stress on Other Components** While the kit strengthens the scavenging system, other parts of the engine (e.g., rods, pistons, or crankshaft) may still be stock. Pushing the engine harder without upgrading these components could lead to premature wear or failure.

6. **Not a "Set-and-Forget" Mod** Unlike simpler mods (e.g., cold air intake), the billet sucker kit requires ongoing attention. You ll need to monitor fuel delivery, ignition timing, and air-fuel ratios to ensure the engine runs smoothly under all conditions.

7. **Resale Value Impact** While the kit adds value to a high-performance build, it may not significantly boost the resale value of a stock or lightly modified vehicle. Buyers looking for simplicity or cost-effective upgrades may avoid a car with such a high-end kit.

### **Conclusion**

The **Arlen Ness MN/CQT1 Billet Sucker Big Kit** is one of the most effective performance upgrades for the 2003 2006 5.7L HEMI engine, offering measurable power gains, durability, and a premium build. However, it is **not a cheap or easy** solution it demands a significant financial investment, careful installation, and proper tuning to avoid drivability issues.

- Enthusiasts who already have a **performance-oriented build** (e.g., headers, intake, or forced induction) and want to further optimize scavenging.

- Those who prioritize **long-term reliability** and are willing to spend the money for a high-quality, billet aluminum solution.

- Owners who plan to **run the engine at higher RPMs or under load** and want to reduce backpressure.

If you re looking for **modest power gains on a budget**, simpler mods (e.g., headers, a high-flow intake, or a tune) may be more practical. However, if you re committed to a **high-performance, durable, and well-supported** upgrade, the Arlen Ness kit is an excellent choice **provided you re prepared for the associated costs and tuning requirements**.

### **Recommendation**

- **If you re building a high-performance 5.7L HEMI (2003 2006 DJ) and want the best scavenging solution:** **Buy the Arlen Ness MN/CQT1 Billet Sucker Kit**, but pair it with a **custom tune, headers, and a high-flow intake** for the best results.

- **If you re on a tighter budget or want simpler gains:** Consider **headers intake tune** first, then evaluate the billet sucker later if you need more power.

- **If you re not mechanically inclined:** Budget for **professional installation and tuning** to avoid mistakes that could damage the engine.

Ultimately, this kit is a **premium upgrade** that justifies its cost for serious performance builds, but it s not a "quick win" it requires planning, investment, and ongoing maintenance to realize its full potential.
