Review AM HIGH QUALITY AUTOPARTS Hydraulic Front Engine Mounts 2pcs Set Bmw L4-2.0l fits 220I 2014–2016

The **AM High A4057 A70019 Hydraulic Front Engine Mounts** are a premium, high-performance upgrade designed specifically for BMW 2 Series Gran Coupe (G41) and 2 Series Touring (G42) models equipped with the L4 2.0L inline-four engine, including the 220i, 228i, and 428i variants from the 2014 2016 model years. Engineered to deliver superior isolation, durability, and a refined driving experience, these mounts replace the stock rubber mounts with a sophisticated hydraulic system that actively dampens engine vibrations, reducing road noise transmission and enhancing cabin comfort while maintaining optimal engine positioning. The hydraulic design incorporates a sealed, self-contained fluid reservoir that absorbs dynamic forces, preventing excessive movement and minimizing the "clunk" often associated with traditional rubber mounts under acceleration, braking, or rough road conditions. Crafted from high-grade materials, including reinforced steel and precision-machined components, these mounts are built to withstand the demanding stresses of daily driving, high-performance use, and extended longevity far exceeding the lifespan of OEM rubber mounts. The installation process is straightforward, requiring only basic tools, and the modular design ensures a perfect fit without the need for modifications, making them an ideal choice for both DIY enthusiasts and professional mechanics. Beyond their functional benefits, these mounts contribute to a more engaging driving experience by reducing engine float and maintaining precise engine alignment, which can improve throttle response and overall vehicle dynamics. Whether you're seeking to eliminate annoying engine noise, enhance ride quality, or simply future-proof your vehicle against wear and tear, the AM High A4057 A70019 hydraulic engine mounts offer a reliable, high-quality solution that elevates both comfort and performance.

### **Pros and Cons of buying a AMS High-Performance A4057 A70019 Hydraulic Front Engine Mounts for BMW N47/N54 (220i, 228i, 428i, 2014-2016 L4 2.0L & N55 3.0L)**

1. **Improved Engine Isolation & Comfort**

- Hydraulic mounts absorb road vibrations more effectively than standard rubber mounts, reducing engine noise and harshness, especially on rough roads or at higher RPMs.

- Helps isolate engine tremors, leading to a smoother cabin experience compared to stock mounts, which can feel stiff and transmit more vibration.

2. **Better Engine Stability & Mounting Feel**

- The hydraulic design provides a firmer yet more controlled mounting feel, reducing excessive movement that can occur with worn stock mounts.

- Some drivers report a slight "floating" sensation at idle, which can be desirable for those who prefer a more refined engine mount feel over the stock rubber s softness.

3. **Compatibility with Performance Modifications**

- These mounts are often used in conjunction with performance upgrades (e.g., turbocharged engines, cold air intakes, or exhaust systems) to prevent excessive engine movement that can occur with increased power.

- The hydraulic damping helps maintain engine alignment under higher loads, reducing stress on the engine bay components.

4. **Durability & Longevity**

- High-quality hydraulic mounts (like AMS) are generally more durable than stock rubber mounts, especially in high-mileage vehicles where the original mounts may already be degraded.

- The hydraulic fluid inside the mounts can last longer than rubber, provided there are no leaks (though fluid degradation over time is still possible).

5. **Easier Installation & Retrofit**

- These mounts are designed as direct replacements for stock mounts, requiring no major modifications to the vehicle.

- Installation is straightforward for those with basic mechanical skills, though some may prefer professional installation to ensure proper alignment.

6. **Positive Feedback from BMW Enthusiasts**

- Many owners of N47/N54/N55 engines report noticeable improvements in engine quietness and stability after upgrading to hydraulic mounts.

- Commonly recommended for vehicles with high mileage or those that have already experienced engine movement issues.

---

1. **Higher Cost Compared to Stock or Aftermarket Rubber Mounts**

- Hydraulic mounts are significantly more expensive than standard rubber replacements (e.g., $100 $200 for a set vs. $30 $80 for rubber mounts).

- The price reflects the engineering and materials used, but it may not be justified for drivers who prioritize cost savings over refinement.

2. **Potential for Fluid Leaks Over Time**

- Hydraulic mounts contain fluid that can degrade or leak, especially if the mounts are subjected to extreme temperatures or rough handling.

- Leaks can lead to loss of damping effectiveness, causing engine rattles or instability. While rare with quality brands like AMS, it is a risk to consider.

3. **Not a Universal Fix for Engine Issues**

- If the engine itself has internal problems (e.g., rod knock, bearing wear), hydraulic mounts will not address these only improve mounting comfort.

- Some drivers may still experience minor engine movement or noise if the mounts are not installed perfectly or if other suspension components are worn.

4. **Slightly Stiffer Feel Than Stock Rubber Mounts**

- While the hydraulic mounts reduce harshness better than stock rubber, they may feel firmer than some drivers prefer, especially at idle.

- Those who like the "soft" feel of stock mounts might find the hydraulic version too stiff, though this is subjective.

5. **Limited Lifespan Compared to Stock Mounts**

- Even high-quality hydraulic mounts will eventually wear out, though typically longer than stock rubber. Replacement intervals may vary, but they are not indefinite.

- Some owners report needing to replace them every 80,000 120,000 miles, depending on driving conditions.

6. **Installation Can Be Tricky for Beginners**

- While not overly complex, installing hydraulic mounts requires careful alignment and torque specifications to avoid damaging the mounts or the engine bay.

- Improper installation can lead to premature failure or ineffective performance.

---

The **AMS A4057 A70019 hydraulic front engine mounts** are a worthwhile upgrade for BMW N47/N54/N55 owners who prioritize engine refinement, stability, and comfort over cost. They excel in reducing vibration, improving mounting feel, and complementing performance modifications. However, they come at a higher price point and require careful maintenance to avoid fluid leaks or premature wear.

- Vehicles with high mileage or worn stock mounts.

- Owners who have added power (turbocharged engines, exhaust systems, etc.) and need better engine isolation.

- Drivers who notice excessive engine movement or noise and want a firmer yet smoother mounting solution.

If your primary concern is **cost savings** or you drive primarily on smooth roads with minimal modifications, standard rubber mounts or even stock replacements might suffice. However, for those seeking a noticeable improvement in engine quietness and stability, the AMS hydraulic mounts are a strong recommendation.

If you are experiencing engine rattles, vibration, or instability in your N47/N54/N55 BMW, or if you plan to add performance parts, **upgrading to the AMS A4057 A70019 hydraulic mounts is a solid choice**. Ensure you follow installation guidelines precisely and monitor for any signs of fluid leaks. For most enthusiasts, the trade-off between cost and improved comfort/stability is justified.
