Review SUBARU Cylinder Head Right Valve Camshaft Housing Oem fits BRZ 2022–2026

The **Subaru 11039AC780 cylinder head right valve camshaft housing** is a precision-engineered component designed specifically for the **2022 2026 model year Subaru BRZ (FA25)**, serving as a critical part of the vehicle s high-performance dual-camshaft, dual-overhead-cam (DOHC) 2.0L FB25 engine architecture. Crafted from high-strength cast aluminum, this housing houses the **right-side valve camshaft**, which plays a pivotal role in the engine s precise valve timing and lift, directly influencing power delivery, throttle response, and overall drivability. The housing features a **tightly machined internal bore** to ensure minimal play and optimal camshaft alignment, while its robust design accommodates the **variable valve timing (VVT) mechanism**, allowing the camshaft to adjust its phase for improved efficiency and performance across the RPM spectrum. The **right-side orientation** distinguishes it from its left-valve counterpart, ensuring proper installation and compatibility with the BRZ s engine bay layout, where the camshafts are positioned symmetrically above the cylinder head. This component is integral to maintaining the engine s **high-revving nature and sport-tuned characteristics**, making it essential for both stock applications and performance modifications. Built to Subaru s stringent quality standards, the housing is engineered for durability, resisting thermal expansion and mechanical stress under the demanding conditions of aggressive driving, track use, or aftermarket upgrades. Whether for routine maintenance, engine rebuilds, or performance enhancements, this cylinder head component ensures reliable operation and contributes to the BRZ s reputation for **precision engineering and driving enjoyment**.

### **Pros and Cons of Buying a Subaru 2022-2026 BRZ Cylinder Head Right Valve Camshaft Housing (Part # 11039AC780)**

1. **Direct Fit Replacement** This part is designed as a direct replacement for the stock camshaft housing on the Subaru BRZ (FA20) model, ensuring proper fitment without modifications.

2. **High-Quality Materials** Subaru OEM parts are built to meet strict manufacturing standards, reducing the risk of premature wear or failure compared to aftermarket knockoffs.

3. **Warranty Coverage** Purchasing from an authorized Subaru dealer or a reputable online retailer may include a warranty, providing peace of mind in case of defects.

4. **Compatibility with Stock Engine** Since it s an OEM part, it integrates seamlessly with the stock FA20 engine, maintaining factory performance and reliability.

5. **Prevents Leaks and Damage** A failing camshaft housing can lead to oil leaks, reduced engine efficiency, or even catastrophic failure. Replacing it proactively avoids costly repairs down the line.

6. **Supports Stock Tuning** If you plan to tune your BRZ, a fresh camshaft housing ensures a solid foundation for forced induction or performance modifications.

1. **Higher Cost** OEM parts are more expensive than aftermarket alternatives, which may be a deterrent for budget-conscious buyers.

2. **Limited Availability** Depending on the retailer, stock may be limited, especially for newer model years, potentially requiring pre-order or longer wait times.

3. **Installation Complexity** Replacing the camshaft housing requires removing the cylinder head, which is a labor-intensive job best left to experienced mechanics unless you have mechanical expertise.

4. **Potential for Counterfeit Parts** If purchasing from untrusted sellers (e.g., eBay, Facebook Marketplace), there s a risk of receiving fake or low-quality parts that could cause further damage.

5. **No Performance Gains** Unlike aftermarket camshafts or intake manifolds, this part does not improve power or throttle response it s purely a maintenance/replacement item.

6. **Environmental Impact** As a new OEM part, it contributes to waste if the old housing is not recycled properly, though this is a minor consideration for most buyers.

### **Conclusion**

The **Subaru 11039AC780 camshaft housing** is a **reliable, high-quality OEM replacement** that ensures proper engine function and prevents potential failures. While it comes at a premium price and requires professional installation, its **direct fit, warranty support, and compatibility with stock tuning** make it a strong choice for owners prioritizing longevity and authenticity.

For those on a tighter budget, **aftermarket alternatives** (e.g., from brands like **Fel-Pro, Sealed Power, or local Subaru specialists**) may offer cost savings without sacrificing quality. However, if you value **brand integrity and long-term reliability**, the OEM part is the safest option.

---

### **Recommendation**

- **Buy from an authorized Subaru dealer or a trusted online retailer** (e.g., **RockAuto, Jegs, or Subaru s official parts site**) to avoid counterfeit parts and ensure warranty coverage.

- **Budget for professional installation** this is not a DIY job for most enthusiasts unless you have cylinder head removal experience.

- **Consider aftermarket options** if cost is a major concern, but verify reviews and compatibility before purchasing.

- **Pair with a full cylinder head service** (valve seals, guides, springs) if the housing replacement is part of a larger engine maintenance project.

Ultimately, this part is a **smart investment for BRZ owners** who want to maintain their engine s health, especially if they plan to keep the car long-term or modify it aggressively.
