Review INFINITI G37 Sedan Rear Bumper Crash Foam Oem Cdg fits 2009–2013

The **Infiniti G37 (2009 2013) Rear Bumper Foam Kit**, specifically the **850921NF0A (for models with a CDG trim, such as the 3.7L V6 or 5.0L V8 variants)**, is a meticulously engineered aftermarket component designed to restore both the structural integrity and aesthetic appeal of your vehicle s rear bumper assembly. This high-quality foam bumper kit is crafted from durable, weather-resistant polyurethane, engineered to withstand the rigors of daily driving, from minor road debris to occasional low-speed impacts. The foam s cellular structure ensures optimal energy absorption, reducing the risk of cracks or warping in the surrounding plastic shell, which is particularly critical for maintaining the bumper s functionality in collision scenarios. Beyond its protective qualities, the foam provides a seamless, factory-like finish, blending seamlessly with the original bumper s contours while offering a slight improvement in rigidity compared to the original, often softer foam inserts. This kit is compatible exclusively with the **G37 platform (2009 2013)**, including models equipped with the **CDG trim designation**, ensuring a precise fit for the rear bumper assembly (part number **850931NF0A**), whether your vehicle is a base trim or a higher-end variant like the **G37x or Touring**. Installation is straightforward, requiring only basic tools, as the foam is designed to snap securely into place within the bumper s internal channels, eliminating the need for adhesives or additional hardware. Whether you re addressing a damaged bumper, upgrading for enhanced durability, or restoring a worn-out original foam, this kit delivers a reliable, long-lasting solution that upholds Infiniti s commitment to performance and refinement.

### **Pros and Cons of buying a Infiniti G37 Rear Bumper Foam (Part Numbers: 850921NF0A, 850931NF0A, CDG) for 2009 2013 Models**

1. **Direct Fitment** These parts are manufactured specifically for the 2009 2013 Infiniti G37 (G37A, G37B, G37C models), ensuring compatibility with the rear bumper assembly, including the foam padding and structural components. No modifications are typically required for installation.

2. **Improved Safety and Protection** The foam bumper padding helps absorb minor impacts, reducing damage to the bumper itself and the vehicle s bodywork in low-speed collisions. This can prevent scratches, dents, or more costly repairs over time.

3. **Aesthetic Restoration** If the original foam has degraded or fallen out, replacing it restores the bumper s original look, preventing a hollow or uneven appearance that can detract from the vehicle s resale value.

4. **Prevents Moisture and Rust** The foam acts as a barrier between the bumper and the vehicle s body, helping to block water, dirt, and road salt from seeping into the bumper s attachment points. This reduces the risk of rust and structural weakening over time.

5. **Cost-Effective Repair** Replacing the foam is significantly cheaper than replacing the entire rear bumper (which can cost several hundred dollars). This makes it a practical solution for minor damage or wear.

6. **Easy Installation** The foam is typically held in place by clips or adhesive, making it a straightforward DIY job for those with basic mechanical skills. No specialized tools are usually required.

7. **Availability of OEM-Quality Parts** These parts are often sourced from reputable suppliers (such as CDG or other aftermarket brands) that specialize in OEM-replacement components, ensuring durability and compatibility.

8. **Long-Term Durability** High-quality foam will last for years, especially if the bumper itself is intact. This avoids repeated replacements and extends the life of the bumper assembly.

1. **Potential for Counterfeit or Low-Quality Parts** Some sellers may offer non-OEM or poorly made foam that degrades quickly, leading to premature failure. Always verify the supplier s reputation and check for authenticity (e.g., matching part numbers and packaging).

2. **Installation Challenges** While generally easy, some G37 models may have slight variations in bumper design (e.g., different clip styles or adhesive requirements). Improper installation could lead to the foam falling out or not fitting securely.

3. **Limited Lifespan of Foam** Even high-quality foam will eventually degrade due to UV exposure, heat, or physical wear. In extreme conditions (e.g., frequent off-roading or harsh climates), replacement may be needed sooner than expected.

4. **Cost Variability** Prices can vary significantly depending on the supplier. While some offer competitive rates, others may charge premium prices for "premium" or "OEM" parts that may not be significantly better.

5. **Compatibility Risks with Modified Vehicles** If the rear bumper has been heavily modified (e.g., with aftermarket parts or custom paint), the foam may not fit perfectly. Always confirm compatibility with your specific bumper setup.

6. **Environmental Factors** Exposure to extreme heat, cold, or prolonged sunlight can cause the foam to crack or become brittle. This may require more frequent inspections or replacements.

7. **Difficulty Finding Exact Matches** While these part numbers cover most 2009 2013 G37 models, there may be slight variations in trim levels (e.g., G37SE vs. G37i) that could affect fitment. Double-check your vehicle s specifications before purchasing.

8. **Potential for Damage During Removal** If the original foam is stuck tightly or the bumper has rusted attachment points, removing it could damage the bumper itself. This might require additional repairs beyond just the foam replacement.

---

Replacing the rear bumper foam on your 2009 2013 Infiniti G37 is a **practical and cost-effective solution** for restoring safety, aesthetics, and structural integrity. The benefits such as improved impact absorption, rust prevention, and ease of installation outweigh the minor drawbacks, provided you source high-quality parts and perform the installation correctly.

However, the cons (e.g., potential for low-quality parts, installation challenges, or environmental degradation) highlight the importance of **researching suppliers, verifying part authenticity, and ensuring compatibility** with your specific vehicle. If the foam is part of a larger bumper repair or replacement project, prioritize using OEM or trusted aftermarket parts to avoid future issues.

---

1. **Purchase from a Reputable Supplier** Stick to well-known brands (e.g., CDG, ACDelco, or other OEM-certified aftermarket parts) and avoid unknown sellers offering significantly lower prices. Websites like **RockAuto, eBay (verified sellers), or Infiniti specialty shops** are good starting points.

2. **Check for Genuine OEM Parts** If budget allows, consider **original equipment manufacturer (OEM) parts** from Infiniti dealerships or authorized recyclers. While slightly more expensive, they offer the best fit and durability.

3. **Inspect the Bumper Before Installation** Ensure the bumper itself is intact and free of major cracks or rust. If the bumper is damaged, address those issues first to prevent the foam from becoming ineffective.

4. **Follow Installation Instructions Carefully** Refer to the vehicle s service manual or the supplier s installation guide. Use the correct tools (e.g., plastic pry tools for clips) to avoid damaging the bumper.

5. **Consider Professional Installation if Needed** If you re unsure about the process, a mechanic familiar with Infiniti models can ensure a proper fit, especially if the bumper has unique features (e.g., integrated sensors or lighting).

6. **Store Spare Foam or Keep a Backup** If your G37 is exposed to harsh conditions, consider keeping a spare foam kit or monitoring the foam s condition during routine inspections.

**Final Verdict:** **Proceed with confidence** if you source quality parts and perform the replacement correctly. The long-term benefits in terms of safety, appearance, and cost savings make this a worthwhile upgrade for most G37 owners. However, if the bumper is severely damaged or the foam is part of a larger repair, prioritize addressing the root cause first.
