Review SUBARU 2.4l Left Driver Side Cylinder Head fits WRX 2022–2023

The **Subaru 11063AC101 2022-2023 WRX 2.4L Left-Driver Cylinder Head** is a precision-engineered component designed exclusively for Subaru s high-performance FA24 flat-four engine, a powerplant renowned for its reliability, turbocharged efficiency, and track-ready capabilities. This cylinder head, manufactured to strict OEM specifications, features a robust cast aluminum construction with integrated cooling passages and optimized combustion chamber geometry to maximize thermal efficiency and power output. The head is equipped with a **left-hand driver configuration**, meaning it is specifically tailored for installation on the driver s side of the engine bay, ensuring proper alignment with the intake and exhaust manifolds, as well as the camshaft and valve train components. The design incorporates **four-valve-per-cylinder architecture**, allowing for improved airflow and scavenging, which is critical for the WRX s turbocharged performance. High-quality **hardened valve seats** and **precision-machined valve guides** are integrated to withstand the extreme pressures and temperatures generated under aggressive driving conditions, whether on the street or at the racetrack. Additionally, the head includes **threaded spark plug holes** and **intake port bosses** that align seamlessly with the FA24 s intake manifold, ensuring optimal fuel-air mixture distribution for peak performance. Built to meet or exceed Subaru s original equipment standards, this cylinder head is a critical replacement part for engines undergoing maintenance, upgrades, or restoration, offering a perfect balance of durability, performance, and compatibility with the WRX s legendary 2.4L turbocharged engine platform.

### Pros and Cons of Buying a Subaru WRX (2022-2023, 2.4L, Left-Hand Drive, Cylinder Head: 11063AC101)

1. **Performance and Driving Dynamics**

The 2.4L naturally aspirated EJ25 engine in the WRX is a fan-favorite, known for its linear power delivery, strong low-end torque, and engaging driving experience. The 2022-2023 models retain the same core engine but feature subtle refinements, such as improved suspension tuning and sharper steering for better handling. The AWD system provides excellent traction in various conditions, making it a versatile daily driver and track car.

2. **Reliability and Durability**

Subaru s EJ25 engine has a long-standing reputation for reliability, especially when properly maintained. The 2.4L version is less prone to the oil consumption issues that plagued some earlier turbocharged EJ25 models. With regular oil changes and attention to minor wear items (like timing chain tensioners), this engine can last well over 200,000 miles. The WRX s robust drivetrain and body structure also contribute to its durability, particularly in rugged or off-road conditions.

3. **Aftermarket Support**

The WRX platform has a vast and mature aftermarket, offering everything from performance parts (intakes, exhausts, suspension upgrades) to tuning solutions. The 2.4L engine benefits from a wide range of bolt-ons, including forced induction kits, which can significantly boost power. The availability of OEM and aftermarket parts makes maintenance and modifications more accessible.

4. **Resale Value**

While not as high as some luxury brands, the WRX holds its value reasonably well, especially in the performance segment. The 2022-2023 models, being newer, will likely retain value better than older generations. The limited production of some variants (e.g., STI or special editions) can also contribute to stronger resale potential.

5. **Safety Features**

Subaru is known for its strong safety ratings, and the WRX includes standard features like EyeSight Driver Assist Technology (adaptive cruise control, pre-collision braking, lane-keeping assist), which enhances both safety and driving confidence. The body-on-frame construction and reinforced chassis provide a sense of security, especially in spirited driving scenarios.

6. **Versatility**

The WRX is a practical choice for those who want a performance car that can also handle daily commuting, road trips, and light off-roading. The AWD system and higher ground clearance (compared to some hatchbacks) make it more capable than many of its rivals. The spacious cabin and practical cargo space are also notable advantages.

7. **Ownership Experience**

Subaru dealerships and independent shops have experience working with WRX models, which can simplify maintenance and repairs. The car s straightforward design (compared to some turbocharged or complex modern engines) means fewer potential points of failure. Additionally, the WRX s reputation in the tuning community fosters a supportive owner network, making it easier to find advice or parts.

1. **Maintenance Costs**

- **Timing Chain and Tensioners:** These are critical components that can wear out over time. Some owners report issues with tensioners or guides, which can lead to timing chain stretch or failure. Replacing them is expensive (often $1,500 $2,500) and should be done as a precaution around 100,000 150,000 miles.

- **Oil Consumption:** Some 2.4L WRX engines, especially those with higher mileage, may burn oil. This isn t as severe as in turbocharged EJ25s but can still add to maintenance costs if not addressed.

- **Suspension and Bushings:** The WRX s aggressive suspension setup can wear out bushings, struts, and control arms faster than in a standard sedan. Replacing these can cost $1,000 $2,000 per corner.

- **Transmission:** The 6-speed manual is robust but can be finicky if not serviced properly. Automatic transmissions (if available) may require more frequent fluid changes.

Overall, ownership costs can add up, especially if the car is heavily modified or driven hard.

2. **Comfort and Practicality Trade-offs**

The WRX prioritizes performance and driving dynamics over comfort. The stiff suspension, loud cabin (especially with the stock exhaust), and limited sound insulation mean it s not the most refined car for daily use. The rear seats are narrow and less spacious than in a sedan, making long trips less comfortable. The lack of a sunroof in some trims can also be a downside for some buyers.

3. **Fuel Economy**

The naturally aspirated 2.4L engine is thirsty compared to modern turbocharged or hybrid alternatives. Expect around **18 22 MPG in the city** and **25 30 MPG on the highway**, depending on driving style and conditions. This is significantly worse than turbocharged WRX models or even some smaller sedans.

4. **Turbocharged Alternatives**

If you re looking for more power, the turbocharged 2.4L WRX (e.g., the STI or turbo models) offers significantly more horsepower (300 HP vs. 271 HP for the NA WRX). While the NA WRX is more engaging to drive, the turbo models provide a more modern performance experience with better fuel efficiency in some cases (though still not great). If you re set on raw power, a turbo WRX may be a better choice.

5. **Depreciation**

While the WRX holds its value better than some performance cars, it still depreciates significantly in the first few years. Buying new or nearly new means you ll pay a premium that may not be fully recovered when selling. Used WRXs (especially those with high mileage) can be found at lower prices, but you ll need to factor in maintenance costs.

6. **Noise and Vibration**

The NA WRX is louder than many modern cars, with noticeable engine and exhaust noise, even at highway speeds. The cabin can feel hollow, and road noise is more pronounced than in a sedan. Vibrations from the engine and drivetrain can also be felt through the pedals and steering wheel, especially at higher RPMs.

7. **Limited Tech Features**

Compared to newer performance cars, the WRX s tech is somewhat dated. Features like infotainment screens, driver aids, and connectivity options are functional but not as advanced as those in rivals like the Mazda MX-5 or Honda Civic Type R. The digital dash is clear but lacks the polish of some competitors.

8. **Potential for Modding Costs**

While the aftermarket is strong, enthusiasts who want to push their WRX to higher power levels (e.g., 400 HP) will face significant costs for upgrades like upgraded intercoolers, fuel systems, and drivetrain components. These modifications can easily exceed $10,000, and they may void warranties or require professional installation.

---

The **2022-2023 Subaru WRX (2.4L, NA, LHD)** is an excellent choice for buyers who prioritize **driving enjoyment, reliability, and aftermarket potential** over fuel efficiency, comfort, or cutting-edge technology. It s a car that thrives on spirited driving, whether on twisty roads, the track, or light off-road adventures. The EJ25 engine s simplicity and strength make it a favorite among enthusiasts, and the WRX s platform is well-suited for modifications.

However, it s not without drawbacks. **Maintenance costs can add up**, especially if you neglect critical components like the timing chain or suspension. The car is **loud, stiff, and less practical** for daily use compared to sedans or SUVs. Fuel economy is poor, and the resale value, while decent, won t match luxury brands.

If you re an **enthusiast who enjoys driving hard, appreciates a classic performance engine, and is willing to invest in maintenance**, the WRX is a fantastic purchase. If you re looking for a **more comfortable, fuel-efficient, or tech-focused car**, you may want to consider alternatives like the **Mazda MX-5 Miata, Honda Civic Type R, or a turbocharged WRX/STI**.
