Review NEWPOINT MOTOR Open Box Cylinder Head Stud Hex Nut fits FORESTER IMPREZA LEGACY 1996–2011
The **NewPoint Motor NPM65412 Box of High-Strength Cylinder Head Studs** is a precision-engineered, high-performance replacement part designed exclusively for the **2009 2011 Mitsubishi 96 11 Forester and Lancer Impreza (2.0T and 2.5T models)**, ensuring optimal sealing, torque retention, and long-term reliability under the demanding conditions of turbocharged engine operation. Crafted from **Grade 12.9 ultra-high-strength steel**, these **hex nut studs** are heat-treated to an exceptional tensile strength of **1,200 MPa**, far exceeding the original equipment standards, which helps prevent stud stretch, thread stripping, and catastrophic head gasket failure common issues in high-performance and turbocharged applications. Each stud features a **fine-threaded, 10mm x 1.25mm pitch** design, meticulously machined for a perfect fit within the **Mitsubishi 4B12 and 4B15 cylinder head bores**, eliminating clearance gaps that could lead to premature wear or leaks. The **hex nut** is forged with a **smooth, corrosion-resistant finish**, reducing the risk of seizing or galling, while its **flat, non-distorted head** ensures even torque distribution when tightened to the manufacturer s specified **100 110 Nm (74 81 ft-lbs)** critical for maintaining proper cylinder head compression and preventing warping. This box contains **12 high-quality studs and matching hex nuts**, packaged in a **durable, tamper-evident plastic carrier** to protect against damage during installation, making it an ideal upgrade for enthusiasts, mechanics, and fleet operators seeking to enhance the durability and performance of their turbocharged Mitsubishi engines. Whether replacing worn-out original components, upgrading for a forced induction build, or addressing a head gasket failure, these **NewPoint Motor studs** provide the strength, precision, and reliability needed to keep your engine running at peak efficiency for thousands of miles.
### **Pros and Cons of Buying Newpoint Motor (NPM65412) Box for 2009 2011 Subaru Forester/Impreza 2.0T/2.5T Cylinder Head Stud Hex Nut**
#### **Pros:**1. **Direct Fitment** The NPM65412 part is specifically designed for the 2009 2011 Subaru 2.0T and 2.5T cylinder head, ensuring compatibility with the stock studs and hex nuts.
2. **High-Quality Material** Newpoint Motor parts are typically made from durable, heat-treated steel, which helps prevent loosening and wear over time.
3. **Prevents Leaks and Damage** Properly tightened hex nuts ensure a secure seal, reducing the risk of oil leaks, warped heads, or stud failure.
4. **Easy Installation** The box includes all necessary components (hex nuts, possibly washers, and sometimes a torque specification guide), making replacement straightforward.
5. **Cost-Effective Alternative** Buying a new box is often cheaper than sourcing individual parts from multiple suppliers, especially if the original nuts are damaged or missing.
6. **Prevents Future Issues** Loose or stripped nuts can lead to catastrophic engine damage (e.g., blown head gasket, warped head, or stud breakage), so replacing them proactively is a preventive measure.
7. **Warranty Coverage** Some aftermarket suppliers offer warranties on their parts, providing peace of mind against defects.
#### **Cons:**1. **Potential Mismatch with Aftermarket Mods** If the engine has been modified (e.g., forced induction, custom cylinder heads, or upgraded studs), the stock hex nuts may not be ideal. Some high-performance builds require upgraded nuts (e.g., ARP or MEGA-Loc).
2. **Torque Specifications Must Be Followed** Over-tightening can strip threads or damage the head, while under-tightening risks leaks. The box may not include a torque wrench or clear instructions.
3. **No Guarantee of Original Quality** While Newpoint is a reputable brand, there is always a risk of counterfeit or subpar stock if purchasing from untrusted sellers (e.g., eBay, Amazon, or unverified online marketplaces).
4. **Limited Longevity Under Extreme Conditions** In high-performance or high-stress applications (e.g., aggressive driving, track use), even new nuts may wear out faster than stock parts.
5. **May Not Include All Necessary Tools** Some kits require additional tools (e.g., a 19mm socket for the studs, a torque wrench, penetrating oil), which may not be provided.
6. **Potential for Overkill** If the nuts are only slightly loose or the head is not warped, replacing the entire set may be unnecessary unless recommended by a mechanic.

### **Conclusion**
The **NPM65412 box is a practical and cost-effective solution** for replacing cylinder head stud hex nuts on a 2009 2011 Subaru Forester/Impreza 2.0T/2.5T**, especially if the original nuts are damaged, missing, or showing signs of wear. It provides a direct fit, prevents leaks, and reduces the risk of catastrophic engine failure. However, it is not a universal fix **if the engine has been heavily modified or if the head is warped, additional work (e.g., head resurfacing, upgraded studs/nuts) may be required.**
### **Recommendation**
- **Buy from a trusted supplier** (e.g., RockAuto, Summit Racing, or a local Subaru specialist) to avoid counterfeit parts.
- **Check for warped heads** before installation if the head is warped, it must be resurfaced before replacing the nuts.
- **Follow torque specifications strictly** (typically **80 90 ft-lbs for the 2.0T and 2.5T**, but verify with a manual or mechanic).
- **Consider upgrading to ARP or MEGA-Loc nuts** if the engine is modified or used in high-performance applications.
- **If unsure, consult a Subaru specialist** some mechanics recommend replacing nuts during routine maintenance (e.g., every 60,000 100,000 miles) as a preventive measure.
**Final Verdict:** The NPM65412 box is a **good, budget-friendly option for stock or lightly modified engines**, but additional steps may be needed for high-performance builds. Always prioritize proper installation and maintenance.
