Review LEXUS Genuine Engine Mount fits RX350 2013–2015

The **Lexus 12360-0P140 Engine Mount** is a precision-engineered, high-performance suspension component designed exclusively for select Lexus models equipped with the 2GR-FKS or 2GR-FE V6 engine configurations, including vehicles such as the Lexus IS 250, RC 250, and GS 250 models produced between the mid-2000s and early 2010s. This mount serves as a critical link between the engine assembly and the vehicle s chassis, ensuring optimal alignment, vibration isolation, and structural integrity while minimizing unwanted noise, vibration, and harshness (NVH) during operation. Crafted from durable, high-grade rubber reinforced with a robust steel core, the 12360-0P140 mount is engineered to withstand the dynamic stresses of high-performance driving, including aggressive acceleration, sharp cornering, and sustained high-speed cruising, all while maintaining precise engine positioning to prevent excessive movement or misalignment. Its design incorporates advanced damping technology to absorb engine vibrations, reducing transfer into the cabin for a quieter, more refined driving experience, particularly noticeable at idle or during low-speed maneuvers. The mount s precise fitment is achieved through a meticulously engineered attachment system, featuring a robust clamp mechanism and corrosion-resistant hardware that ensures long-term reliability even in demanding environments. Whether installed as part of a routine maintenance procedure or as a replacement due to wear, fatigue, or damage, this OEM-quality engine mount upholds Lexus s commitment to engineering excellence, delivering both performance and durability for the discerning driver.

**Pros and Cons of Buying a Lexus 12360-0P140 Engine Mount**

The **Lexus 12360-0P140** is an engine mount (also referred to as an engine support strut or isolator) designed for certain Lexus models, particularly those with the **2GR-FKS or 2GR-FE V6 engine** (e.g., RX 350, LC 500, GS 350, etc.). Below is a detailed breakdown of its advantages and disadvantages, followed by a conclusion and recommendation.

---

### **Pros of buying a Lexus 12360-0P140 Engine Mount**

1. **OEM Quality and Fitment**

- This is an **original equipment manufacturer (OEM) part**, meaning it is designed to match Lexus s exact specifications for your vehicle. It ensures proper alignment, vibration damping, and engine support, reducing the risk of misfit issues that can occur with aftermarket parts.

- The mount is engineered to work seamlessly with the **2GR engine family**, which is known for its smooth operation and reliability. Proper mounting helps maintain the engine s balance and reduces unnecessary stress on related components (e.g., suspension, transmission mounts).

2. **Durability and Longevity**

- Lexus engine mounts are built to last the lifetime of the vehicle under normal conditions. The **12360-0P140** is constructed with high-quality rubber and reinforced steel components, designed to withstand the vibrations and loads of a V6 engine.

- Unlike cheaper aftermarket mounts, which may degrade faster due to inferior materials, the OEM part is less likely to fail prematurely, reducing the need for frequent replacements.

3. **Reliability and Safety**

- A failing engine mount can lead to **excessive engine movement**, which may cause damage to the **transmission, exhaust, or suspension components**. Replacing a worn mount with an OEM part restores proper engine positioning, improving safety and preventing costly secondary damage.

- The mount s design helps **isolate engine vibrations**, contributing to a quieter cabin and reducing driver fatigue over long drives.

4. **Warranty Coverage**

- If purchased directly from Lexus or an authorized dealer, the **12360-0P140** may come with a **factory warranty**, typically covering defects in materials or workmanship for a set period (e.g., 3 5 years or the life of the vehicle, depending on the seller).

- Some third-party sellers (e.g., RockAuto, Amazon, or specialty auto parts stores) may offer warranties as well, though these vary by provider.

5. **Easy Installation**

- The mount is a **direct replacement part**, meaning it is designed to drop-in without extensive modifications. Most mechanics or even experienced DIYers can install it in **1 2 hours**, especially if they have access to basic tools (e.g., jack, jack stands, torque wrench).

- Lexus provides **service manuals and diagrams** that make installation straightforward for those familiar with automotive repairs.

6. **Compatibility with Upgrades**

- If you plan to modify your vehicle (e.g., **tuning, exhaust upgrades, or suspension changes**), a proper OEM mount ensures that the engine remains securely positioned. This is critical for maintaining **engine balance** and preventing issues like **transmission misalignment** or **exhaust flexing**.

7. **Resale Value Preservation**

- Using OEM parts when performing maintenance or repairs helps **maintain the vehicle s condition** in the eyes of potential buyers. A well-documented service history with genuine Lexus parts can **increase resale value** compared to a car with mixed or aftermarket components.

---

### **Cons of buying a Lexus 12360-0P140 Engine Mount**

1. **Higher Cost Compared to Aftermarket Alternatives**

- The **12360-0P140** is significantly more expensive than many aftermarket engine mounts. Prices typically range from **$100 $200** for the part alone, depending on the seller (authorized dealer vs. online retailer).

- Aftermarket mounts (e.g., from **Fel-Pro, Dorman, or Mopar**) often cost **$30 $80 each**, making them a more budget-friendly option for some buyers.

2. **Potential for Counterfeit or Low-Quality Parts**

- Purchasing from **unauthorized sellers** (e.g., eBay, Craigslist, or unscrupulous online marketplaces) increases the risk of receiving a **counterfeit or substandard part**. These fakes may fail prematurely or not fit correctly, leading to further damage.

- Always verify the seller s reputation and ensure the part has a **serial number or Lexus part number** to confirm authenticity.

3. **Limited Availability Outside Dealerships**

- While the part is widely available online (e.g., **RockAuto, Amazon, eBay**), some **local auto parts stores** may not stock it, forcing buyers to order online. Shipping times can add to the overall cost and inconvenience.

- If you need the part **immediately** (e.g., for a roadside repair), an aftermarket option or a rental service might be more accessible.

4. **Potential for Overkill for Minor Issues**

- If the mount is **only slightly worn** (e.g., minor cracking or slight sagging), some drivers may consider **delaying replacement** or opting for a **cheaper aftermarket part** instead. However, this is not recommended, as even minor failures can lead to **engine movement and secondary damage**.

- If the mount is **completely failed** (e.g., rubber completely degraded, metal parts bent), replacement is **non-negotiable** for safety reasons.

5. **Installation May Require Professional Help**

- While the part is easy to install, **removing the old mount** can be tricky if it is **seized or corroded**. Some drivers may need to **spray penetrating oil (PB Blaster)** or use a **mount removal tool** to avoid damaging the engine or transmission.

- If you re not comfortable with automotive repairs, hiring a mechanic may add **$50 $150 in labor costs**, depending on the shop s rates.

6. **Environmental and Ethical Concerns**

- OEM parts are **not always eco-friendly**, as they contribute to **electronic waste** when disposed of improperly. Some buyers may prefer **recycled or aftermarket parts** as a more sustainable choice.

- There is also an **ethical debate** over supporting dealerships vs. independent mechanics or aftermarket suppliers, though this is subjective.

---

### **Conclusion**

The **Lexus 12360-0P140 engine mount** is a **high-quality, reliable, and safe choice** for owners of **2GR-FKS/FE V6 Lexus models**. Its **OEM status ensures proper fitment, durability, and compatibility** with the engine s design, making it the **best long-term solution** for maintaining vehicle integrity. While it comes at a **higher upfront cost** than aftermarket alternatives, the **reduction in risk of engine damage, improved safety, and preservation of resale value** justify the investment for most serious owners.

However, if you are on a **tight budget** or the mount is **only mildly worn**, an **aftermarket part from a reputable brand** (e.g., **Fel-Pro, Mopar, or Dorman**) may be a **cost-effective compromise**. Always **verify the seller s legitimacy** to avoid counterfeit parts, and **prioritize safety** a failing engine mount can lead to **expensive repairs** if ignored.

For **most Lexus owners**, the **12360-0P140 is the recommended choice** due to its **proven reliability, warranty coverage, and peace of mind**. If purchasing from a **non-dealer source**, ensure the part is **genuine** and comes with proper documentation.
