### **Pros and Cons of buying a Mitsubishi MR574335 Upper Plate**

1. **Compatibility and Fitment** The MR574335 is a widely recognized upper plate for Mitsubishi engines, particularly those in the 4G63, 4A92, and 4B11 series (common in models like the Lancer, Eclipse, and Galant). Its design ensures a proper fit, reducing the risk of misalignment or improper installation.

2. **Durability and Strength** Mitsubishi s upper plates are typically forged from high-quality steel, offering better resistance to warping, cracking, or deformation under high engine loads. This makes it a reliable choice for high-performance or modified engines.

3. **Performance Benefits** A properly installed upper plate can improve valve train rigidity, reduce valve float at high RPM, and enhance overall engine durability. This is especially useful for forced induction applications (turbocharged or supercharged engines).

4. **Ease of Installation** Compared to some aftermarket alternatives, the Mitsubishi OEM upper plate is straightforward to install, especially for those familiar with engine rebuilds. It often comes with gaskets or seals, simplifying the process.

5. **Cost-Effective for OEM Replacement** If your engine s original upper plate is damaged (e.g., from a blown head gasket or valve train failure), replacing it with the genuine Mitsubishi part is often cheaper than buying a full engine rebuild kit or aftermarket alternative.

6. **Warranty and Reliability** As an OEM part, it comes with Mitsubishi s quality assurance, reducing the risk of premature failure compared to some lower-quality aftermarket options.

1. **Limited Availability and Lead Times** Mitsubishi parts, especially older or discontinued models, can be hard to find in stock. Prices may fluctuate due to demand, and shipping delays are possible, especially if ordering from overseas.

2. **Potential for Overkill** If your engine is stock or lightly modified, the MR574335 might be more robust than necessary. For stock applications, a less expensive aftermarket upper plate (if compatible) could suffice without sacrificing performance.

3. **Weight Considerations** Being a forged steel part, it is heavier than some aluminum aftermarket alternatives. While this adds strength, it may not be ideal for engines where weight reduction is a priority (e.g., high-performance street or racing applications).

4. **Compatibility with Aftermarket Components** Some aftermarket camshafts, lifters, or valve springs may not fit perfectly with the MR574335 due to slight dimensional differences. Always verify compatibility before purchasing.

5. **Cost Compared to Aftermarket Options** While not excessively expensive, the Mitsubishi OEM part may be pricier than certain aftermarket alternatives that offer similar performance at a lower price. Researching budget-friendly brands (e.g., JE, Scat, or local manufacturers) could save money without sacrificing quality.

6. **Potential for Misuse** If installed incorrectly (e.g., improper torque specs, missing gaskets, or incorrect alignment), the upper plate could lead to leaks, warping, or even catastrophic failure. Proper installation knowledge is essential.

### **Conclusion**

The **Mitsubishi MR574335 upper plate** is a solid, reliable choice for those rebuilding or modifying Mitsubishi engines, particularly in the 4G63, 4A92, or 4B11 families. Its strength, durability, and OEM quality make it a trusted option for serious builders, though it may not be the most cost-effective or lightweight solution for stock or minimal modifications. If you prioritize longevity, performance, and ease of installation, this part is a strong recommendation. However, if budget or weight is a concern, exploring high-quality aftermarket alternatives could be worthwhile just ensure they meet your engine s specific requirements.

### **Recommendation**

- You prefer the peace of mind of a genuine Mitsubishi component.
