GSC Power-Division 2022+ Subaru WRX FA24F 36mm Head (STD) 104.8mm Long Chrome Polished Intake Valve - Set of 8
Upgrade the intake valves in your 2022 and later Subaru WRX with the FA24F 2.4L turbo engine using this set of 8 GSC Power-Division STD valves. Each valve features a 36mm head diameter, 104.8mm total length, and 5.46mm stem diameter for precise fit and enhanced engine performance. These valves provide higher airflow through advanced head design and maintain sealing under high stress for reliable power gains.
Key Features
- Swirl Polished Heads: Engineered for smoother airflow, optimizing the valve's aerodynamics.
- Back Cut Design: Strategically reduces valve weight, enabling higher RPMs.
- Micro-Polished Valve Stems: Minimizes oil retention on the stem, reducing drag for a smoother motion within the guide.
- Premium Material: Intake valves are crafted from modified 21-4N stainless steel for exceptional strength and performance.
- Advanced Valve Tips: Hardened or fused with a stellite wafer tip, ensuring extended life and minimal wear, maintaining proximity to the rocker or valve tappet.
- Optimized Valve Tip Lengths: Meticulously adjusted for specific applications to reduce tipping and maintain proper valve train geometry, thereby streamlining valve lash adjustment during installation.
- Balanced Keeper Groove: Precisely adjusted to balance intake and exhaust spring pressures, minimizing the need for valve spring shims. This optimization maximizes performance from our spring and retainer kits.
- Compatibility: Our valves seamlessly work with OEM keeper/lock systems. While not mandatory, we advise against reusing any valve lock on performance applications due to potential material grooving.
- Quality: Backed by GSC Power-Division's commitment to quality and performance.
Product Notes
- Flow tested prototype heads ensure highest airflow for FA24F applications with less face distortion for better sealing.
- Designed for longevity with reduced valve weight and advanced materials to handle extreme conditions.
- Carefully packaged to protect polished finishes during transit.
Installation Notes
- Professional installation recommended.
