Review MOPAR Dodge Chrysler Plymouth Nos Switching Valve Hose fits 318 360 1978–1979

The **Mopar 4095535** is a precision-engineered switching valve hose designed exclusively for the **1978 and 1979 Dodge, Chrysler, and Plymouth full-size vehicles** equipped with the iconic **318 cubic-inch and 360 cubic-inch inline-six (I6) engines**, particularly those featuring the **NOS (Nitrous Oxide System)** or high-performance applications. This hose serves as a critical component in the **nitrous oxide injection system**, ensuring seamless fluid transfer between the nitrous oxide tank and the intake manifold while maintaining optimal pressure and flow. Crafted from **high-grade rubber with reinforced synthetic fibers**, this hose is built to withstand the demanding conditions of high-performance driving, including extreme temperatures, rapid pressure fluctuations, and prolonged exposure to fuel and oil residues. Its **durable construction** prevents kinking, cracking, or premature failure, which could lead to system malfunctions, reduced engine performance, or even catastrophic nitrous oxide leaks. The **snug-fitting fittings** on both ends designed for compatibility with standard **SAE-style quick-connect or threaded connections** ensure a secure and leak-proof seal, allowing for quick installation and removal without the need for specialized tools. Whether you're restoring a classic muscle car, upgrading an engine for street performance, or maintaining a high-output NOS setup, this **OEM-replacement hose** delivers the reliability and performance expected from Mopar, the trusted name in automotive aftermarket parts. Its **universal fitment** across multiple model years and engine configurations makes it an essential upgrade for enthusiasts seeking to enhance throttle response, torque output, and overall drivability while preserving the integrity of their engine s nitrous oxide system.

### **Pros and Cons of buying a Mopar 4095535 NOS Switching Valve Hose (1978-1979 Dodge, Chrysler, Plymouth 318/360)**

#### **Pros:**

1. **Original Equipment Quality (OEM)** Since this is a **New Old Stock (NOS)** part, it was manufactured to the same specifications as the original components used in 1978-1979 vehicles. This means it should fit perfectly without modifications and maintain the intended performance of the engine s vacuum switching system.

2. **Reliability and Durability** Mopar NOS parts are known for their robustness. The switching valve hose is a critical component in the **vacuum-operated valve lifter system** (used in some 318 and 360 engines), and a high-quality hose ensures proper vacuum flow, preventing lifter rattle and engine wear.

3. **Easy Installation** Being a direct replacement, installation is straightforward. No cutting, welding, or custom fitting is required, making it a simple DIY job for most mechanics or even an experienced car owner.

4. **Compatibility with Aftermarket Mods** If you plan to modify your engine (e.g., swapping in a performance camshaft or adjusting valve lash), a fresh NOS hose ensures the vacuum system functions correctly, supporting aftermarket upgrades.

5. **Avoiding Counterfeit or Low-Quality Replacements** Many aftermarket hoses may be made from inferior materials or improperly sized, leading to leaks or premature failure. A genuine Mopar NOS part eliminates this risk.

6. **Preservation of Originality** If you re restoring a classic vehicle to factory specifications, using NOS parts helps maintain authenticity, which is valuable for collectors and enthusiasts.

7. **Potential for Future Resale Value** If you ever sell the vehicle, having NOS components can increase its appeal to purists and collectors, justifying a higher asking price.

#### **Cons:**

1. **Cost Compared to Aftermarket Alternatives** NOS parts are significantly more expensive than generic or aftermarket replacements. While they justify the price with quality, budget-conscious buyers may opt for cheaper (though potentially lower-quality) alternatives.

2. **Limited Availability** NOS inventory can be scarce, especially for older Mopar parts. If you don t find it quickly, you may need to wait or consider a used replacement, which could be less reliable.

3. **Potential for Overkill** If the hose is only a minor wear item (e.g., slight cracking but still functional), replacing it with a NOS part may be unnecessary unless you re doing a full restoration or engine rebuild.

4. **Storage and Handling Risks** NOS parts are often stored in warehouses for years, which can sometimes lead to minor wear (e.g., slight discoloration or dust accumulation). While this doesn t affect performance, it may not look as pristine as new aftermarket parts.

5. **No Warranty (or Limited Warranty)** Unlike some aftermarket brands that offer warranties, NOS parts typically come with no warranty, meaning you bear the full responsibility if they fail prematurely.

6. **Potential for Misidentification** If the part number is incorrect or the wrong year/model variant is purchased, it may not fit properly. Always double-check compatibility before buying.

7. **Environmental and Ethical Concerns** Some NOS parts come from salvage yards or dismantlers, raising questions about the source. While Mopar NOS parts are generally ethically sourced, it s worth considering if sustainability is a priority.

### **Conclusion:**

The **Mopar 4095535 NOS switching valve hose** is an excellent choice if you prioritize **reliability, authenticity, and long-term performance** for your 1978-1979 Dodge, Chrysler, or Plymouth engine. It is the best option for **restorations, serious modifications, or maintaining factory specifications**, though it comes at a premium cost.

However, if you re on a tight budget or the hose is only a minor issue, an **aftermarket replacement** (from a reputable brand like **Mopar Performance, Moroso, or Stan s**) may suffice. These alternatives are often more affordable and still offer good quality, though they may not carry the same prestige as NOS.

For most **enthusiasts and restorers**, the **pros outweigh the cons**, making the NOS part the **best long-term investment**. For casual drivers or those doing minor repairs, a **high-quality aftermarket hose** could be a practical compromise.

### **Final Recommendation:** - **Buy the NOS part if:**

- You re restoring or maintaining a classic vehicle to factory specs.

- You want the highest possible reliability and compatibility.

- You re willing to pay the premium for OEM-quality components.

- **Consider an aftermarket alternative if:**

- You re on a budget and the hose is only a minor issue.

- You re not concerned about strict authenticity.

- You can find a well-reviewed aftermarket hose (e.g., **Mopar Performance, Moroso, or Stan s**) that fits your needs.

For most **serious builders**, the **NOS part is the best choice** it s worth the investment for peace of mind and long-term performance.
