### **Pros and Cons of buying a JBR MZ3MS3FNA-PMM-5 (2010 2013 Mazda Speed Passenger Motor Mount, 70 Durometer)**

1. **High-Quality Material and Construction** The 70 durometer rubber compound is designed to provide a balance between stiffness and flexibility, reducing excessive vibration while maintaining structural integrity. This is particularly useful for high-performance applications where a softer mount might lead to excessive movement.

2. **Direct Fitment for 2010 2013 Mazda Speed Models** The part is specifically engineered for the MZ3MS3FNA platform (Mazda3 hatchback, Mazda5, and Mazda Speed3), ensuring proper alignment and compatibility without requiring modifications.

3. **Improved Engine Mounting Stability** A well-designed passenger-side motor mount helps isolate engine vibrations, reducing road noise and harshness in the cabin. This can enhance driving comfort, especially on rough roads or at higher speeds.

4. **Durability and Longevity** JBR (John Bean Rubber) is a reputable manufacturer known for producing high-quality rubber components that resist degradation from heat, oil, and environmental factors. A properly installed mount should last the life of the vehicle if maintained correctly.

5. **Potential Performance Benefits** For enthusiasts, a stiffer or more precise mount can help reduce engine movement, which may improve drivetrain alignment and reduce wear on related components like the subframe or transmission mounts.

6. **Easy Installation** As a direct-fit replacement, this mount should be relatively straightforward to install, though some mechanical skill and basic tools (like a jack and jack stands) may be required. Installation guides and videos are typically available from the manufacturer.

7. **Warranty and Support** JBR offers warranties on their products, and their customer service is generally responsive for issues related to manufacturing defects. This provides peace of mind for buyers.

1. **Cost Compared to OEM** While not excessively expensive, this aftermarket part will likely cost more than an original equipment manufacturer (OEM) motor mount. For example, an OEM Mazda motor mount might range from $30 $60, whereas this JBR part typically retails for $80 $120, depending on the source and retailer markup.

2. **Potential for Over-Tightening** Some aftermarket mounts, especially stiffer ones, can be more sensitive to installation torque. Over-tightening the bolts can damage the rubber or even crack the mount, leading to premature failure. Proper torque specifications must be followed (usually around 60 80 ft-lbs, but always check the vehicle s service manual).

3. **Limited Availability of Replacement Parts** If the mount fails prematurely, finding an exact replacement may be difficult, though JBR is a well-established brand with a good track record for reliability.

4. **Installation Challenges for DIYers** While the part is a direct fit, the installation process involves lifting the vehicle and accessing the engine bay, which can be tricky for those without experience. Improper installation (e.g., not aligning the mount correctly or not securing it properly) can lead to vibration issues or even detachment.

5. **Durability Concerns Over Time** Although JBR is known for quality, rubber components can degrade over time due to heat, oil exposure, or age. If the vehicle is driven aggressively or in extreme conditions (e.g., off-roading, towing), the mount may wear out faster than expected.

6. **Potential for Excessive Stiffness** A 70 durometer mount is stiffer than stock OEM mounts (which are often around 50 60 durometer). While this can reduce vibration, it may also transmit more engine noise and harshness to the cabin, which some drivers may find less comfortable.

7. **Compatibility with Modifications** If the vehicle has been heavily modified (e.g., lowered suspension, custom exhaust, or performance upgrades), the stock motor mount alignment might not be ideal. In such cases, a custom or aftermarket mount designed for the specific modifications may be necessary.

The **JBR MZ3MS3FNA-PMM-5 (70 durometer) passenger motor mount** is a solid aftermarket replacement for 2010 2013 Mazda Speed models, offering improved vibration damping, durability, and compatibility. It is particularly well-suited for drivers who prioritize engine stability, reduced road noise, and long-term reliability. However, it comes at a higher cost than OEM parts and requires careful installation to avoid issues like over-tightening or improper alignment.

For most owners, this mount is a worthwhile upgrade especially if the original mount is worn or leaking. However, if budget is a concern, an OEM or lower-cost aftermarket alternative (e.g., a 60 durometer mount) might suffice for basic replacement needs.

---

- You re experiencing excessive engine vibration, rattles, or noise in your cabin.
