Review PORSCHE OEM 87-95 Driver Side Door Armrest Ac Heating Air Vent Grill Left fits 928

The **Porsche 928.574.087.03 driver-side armrest assembly (model years 1987 1995, 928 S4 variant)** represents a meticulously engineered component from one of Porsche s most refined and understated grand tourers. This rare and highly sought-after part is integral to the left-side door architecture of the **928 S4**, a model that distinguished itself with its 5.4-liter air-cooled flat-12 engine, producing a commanding 408 horsepower and a torque-heavy 390 lb-ft enough to propel the 928 through curves with effortless poise while maintaining a near-silent cabin. The armrest itself is a study in functional elegance, crafted from high-quality materials that align with Porsche s commitment to durability and driver-centric ergonomics. Its design incorporates a **contoured, padded surface** with a textured grip, ensuring comfort during long drives while also providing a secure handhold for the driver. Beneath the soft-touch upholstery, the armrest features a **reinforced metal frame**, engineered to withstand the stresses of daily use, from aggressive cornering to the occasional bump on winding roads. The inclusion of an **integrated air vent grill** a subtle yet distinctive detail speaks to the 928 s attention to detail, allowing for subtle airflow to the driver s side, enhancing comfort without compromising the car s aerodynamic efficiency. This vent grill is not merely decorative; it is a functional element, contributing to the car s climate control system by directing air from the **heating and air conditioning unit** (AC) directly to the driver s reach, ensuring optimal temperature regulation even during extended journeys. The **left-side placement** of this armrest is particularly significant, as it aligns with the 928 s left-hand-drive configuration, a detail that further emphasizes its authenticity and compatibility with the vehicle s original specifications. Whether restoring a classic 928 S4 to its former glory or upgrading an existing unit, this armrest assembly is a testament to Porsche s engineering precision, blending performance, luxury, and timeless craftsmanship into a single, indispensable component.

### **Pros and Cons of Buying a Porsche 928 (S4, Driver s Side Armrest, AC, Heating, Vent, Grill Left, 1987 1995)**

#### **Pros**

1. **Exceptional Engine and Performance**

The 928 features a naturally aspirated 5.4L (or 6.0L in later models) air-cooled flat-12 engine, producing **370 415 hp** depending on the year. This engine delivers smooth, linear power with a distinctive exhaust note, offering a driving experience that feels both luxurious and sporty. The S4 variant (1990 1995) further enhances performance with a revised engine and suspension, making it one of the fastest 928s.

2. **Luxury and Comfort**

The 928 is a grand tourer with a spacious, well-appointed interior featuring high-quality materials, leather seats, and a refined cabin. The driver s side armrest (a rare feature in this model) adds convenience for long drives. The car was designed with comfort in mind, making it suitable for both highway cruising and spirited driving.

3. **Reliability (For Its Era)**

While not as bulletproof as modern German cars, the 928 s air-cooled flat-12 engine is known for longevity if properly maintained. Many examples with **under 100,000 miles** can still run strong with regular oil changes and valve adjustments. The S4 s upgraded internals (including a revised crankshaft and connecting rods) make it more robust than earlier models.

4. **Classic Grand Tourer Appeal**

The 928 is a cult favorite among enthusiasts for its blend of performance, luxury, and timeless design. Its **aerodynamic bodywork, pop-up headlights, and aggressive stance** make it visually striking. Owning one allows you to stand out while enjoying a car that was ahead of its time in both engineering and aesthetics.

5. **Modding Potential**

The 928 has a dedicated aftermarket, offering upgrades for suspension, exhaust, intercoolers, and even engine modifications (though these can be expensive). Performance parts like **ECU tuning, forced induction (rare but possible), and lightweight wheels** can enhance its already impressive capabilities.

6. **Low Mileage Examples Available**

Due to its niche appeal, well-maintained 928s especially S4s can be found with **under 50,000 miles**, making them more practical for daily driving than many classic Porsches.

7. **Resale Value (For Enthusiasts)**

While not as high as a 911 or 917, the 928 holds value among collectors, particularly the S4 and later models. A properly documented example can appreciate over time, especially if it remains in good condition.

---

#### **Cons**

1. **High Maintenance Costs**

The air-cooled flat-12 engine requires **regular valve adjustments (every 15,000 20,000 miles)**, which can cost **$500 $1,200 per service**. Other common issues include:

- **Timing chain stretch** (can lead to catastrophic engine failure if ignored).

- **Water pump failures** (often require a full engine removal for replacement).

- **Exhaust manifold cracks** (especially in older models).

- **Electrical gremlins** (early 928s had issues with wiring and sensors).

The S4 mitigates some of these problems but is not immune to age-related wear.

2. **Fuel Economy is Poor**

Expect **12 15 MPG highway** and **9 12 MPG city** in a naturally aspirated 928. The S4 is slightly better but still thirsty. This makes long-distance driving expensive, especially with modern fuel prices.

3. **Complexity and Specialized Mechanics**

Finding a qualified Porsche mechanic familiar with the 928 can be difficult. Many dealerships and shops focus on newer models, forcing owners to rely on specialists or do much of the work themselves.

4. **Weight and Handling**

The 928 is **heavy (3,200 3,500 lbs)**, which affects acceleration and handling compared to lighter sports cars. While the S4 improves responsiveness, it still lacks the nimbleness of a 911 or a modern GT car. The suspension is firm but can feel harsh over rough roads.

5. **Parts Availability and Cost**

While not as scarce as parts for a 917 or early 911, the 928 s parts can be **expensive**. Replacement items like **seals, gaskets, and even entire subframes** may cost **hundreds to thousands of dollars**. Buying a car with a **full parts inventory** is wise.

6. **Insurance Can Be Expensive**

Due to its high value and performance, insuring a 928 especially an S4 can be costly. Some insurers may require **specialized coverage** or higher deductibles.

7. **Not a Practical Daily Driver for Everyone**

The 928 is **not as fuel-efficient, comfortable on long trips, or easy to park** as a modern luxury car. Its size (similar to a small SUV) and weight make it less ideal for urban driving or those who prioritize convenience.

8. **Potential Hidden Issues**

- **Engine oil leaks** (from valve cover gaskets or rear main seal).

- **Transmission wear** (especially in automatic models).

- **Rust** (check wheel wells, undercarriage, and frame).

- **Electrical faults** (early models had poor grounding and wiring issues).

- **Suspension wear** (shocks, bushings, and struts degrade over time).

---

### **Ending Conclusion**

The **Porsche 928 (especially the S4)** is a **fantastic car for the right owner** someone who appreciates **luxury, performance, and classic engineering** and is willing to invest time and money in maintenance. It s not a **plug-and-play daily driver** like a modern Audi or BMW, but it offers a **unique blend of power, comfort, and character** that few cars can match.

- Have **mechanical experience** or access to a **trusted Porsche specialist**.

- Can afford **regular maintenance** (valve adjustments, oil changes, potential major repairs).

- Are okay with **higher fuel costs and insurance**.

- Enjoy **driving a statement car** that turns heads.

- Want a **project car with long-term potential** (if well-documented).

then the 928 is an **excellent purchase**.

- Need a **low-maintenance, fuel-efficient daily driver**.

- Don t have the **budget for unexpected repairs**.

- Prefer **modern convenience** (easy parking, long trips, tech features).

- Want a **car that s easier to insure or sell**.

then consider alternatives like a **911, 944, or a modern GT car** that may be more practical.

---

### **Recommendation**

You ve **thoroughly inspected the car** (preferably with a mechanic who knows the model).

It has **low miles (under 80,000)** and **complete service records**.

The **engine runs smoothly** (no ticking, oil leaks, or exhaust smoke).

The **transmission shifts cleanly** (if automatic).

You re **prepared for maintenance costs** and have a **plan for long-term care**.

You **love the 928 s character** and don t mind its quirks.

- **1990 1995 (S4 models)** More power, revised internals, and better reliability than early 928s.

- **1988 1991 (non-S4)** Still desirable but may require more attention.

- Cars with **excessive miles (over 150,000)** without full maintenance history.

- Examples with **known engine issues** (timing chain stretch, water pump failures).

- Those missing **critical parts** (e.g., no spare wheels, missing interior components).

The **928 is a dream car for enthusiasts**, but it s **not a "set it and forget it" purchase**. If you re **passionate about Porsches, have the means to care for it, and want a unique blend of luxury and performance**, it s a **fantastic investment**. For everyone else, it may be **too much hassle for the daily drive**.

Would you like guidance on **what to look for during an inspection** or **where to find reliable mechanics** for this model?
