Description

The EM-4964 Rear LH Engine Mount is a precision-engineered replacement part designed to suit the BMW 320i 2.0L, offering a perfect balance of durability, vibration control, and OEM-level fitment. Manufactured by Boonma, a trusted name in automotive components, this mount is built to meet or exceed original specifications, making it an ideal choice for both maintenance and restoration projects.

⚙️ Purpose & Function

Engine mounts are critical components that secure the engine to the chassis while isolating vibrations and absorbing road shocks. The rear left-hand (LH) mount plays a key role in stabilizing the engine under acceleration, braking, and cornering. In the BMW 320i, particularly models such as the E90 series (2004–2007) with the N46B20 2.0L engine, the EM-4964 ensures that the drivetrain remains properly aligned, contributing to smooth power delivery and reduced cabin noise.

🧩 Compatibility & Fitment

The EM-4964 is designed for rear left-hand positioning and is compatible with selected BMW 3 Series models, including the E90 320i 2.0L petrol in both manual and automatic transmissions. Built to OEM dimensions, it offers a direct bolt-on replacement without the need for modifications, ensuring a hassle-free installation process.

🛠️ Construction & Materials

Boonma’s EM-4964 features a reinforced rubber compound bonded to a high-strength steel bracket. This combination provides excellent resistance to heat, oil, and mechanical stress—common challenges in the engine bay. The rubber engineers to absorb and dampen vibrations effectively, while the steel housing ensures structural integrity under load. This robust design helps extend the lifespan of the mount compared to lower-quality alternatives.

🚗 Performance Benefits

Replacing a worn or damaged rear LH engine mount with the EM-4964 offers several advantages:

• Reduced vibration and noise inside the cabin
• Improved drivetrain stability during acceleration and gear changes
• Protection for surrounding components such as exhaust systems, hoses, and wiring
• Restored factory-like driving comfort and handling precision

A failing mount can cause excessive engine movement, leading to premature wear on other parts and a less refined driving experience. The EM-4964 restores the original balance and comfort expected from a BMW.

🧰 Installation & Maintenance

While installation can perform by skilled DIY enthusiasts, professional fitting recommends to ensure correct torque settings and alignment. For best results, it’s advisable to inspect and, if necessary, replace both rear mounts at the same time to maintain even support.

In summary, the EM-4964 Rear LH Engine Mount is a high-quality, cost-effective solution for BMW 320i owners seeking to maintain performance, comfort, and reliability.
