Overview:

The GSC Power Division Intake Valve is a precision-engineered upgrade designed specifically for the FA20 engine found in the Scion FR-S, Subaru BRZ, and Toyota 86 models within the specified year ranges. Crafted to enhance your engine’s breathing capabilities, these intake valves feature a chrome polish finish and a slightly larger 36mm head diameter, increasing by 1mm over stock dimensions. This set of 50 valves is ideal for performance enthusiasts seeking improved airflow and durability in their naturally aspirated or mildly tuned FA20 engines.

Whether you are a daily driver looking to maintain reliability while gaining a slight edge in throttle response or a spirited driver aiming to support higher RPM power, these intake valves provide a solid foundation for engine performance improvements.

Key Features:

These intake valves offer several technical advantages that contribute to enhanced engine efficiency and longevity:

• Manufactured by GSC Power Division, a trusted name in high-performance engine components.
• Chrome polished finish reduces friction and resists wear, promoting smoother valve operation and extended service life.
• 36mm valve head diameter, increased by 1mm over factory valves, allowing for improved airflow into the combustion chamber.
• Precision engineering ensures exact fitment and compatibility with the FA20 engine found in Scion FR-S (2013–2016), Subaru BRZ (2013–2020), and Toyota 86 (2017–2020).
• Set of 50 valves included, suitable for complete engine rebuilds or multiple valve replacements.
• Designed to support enhanced engine breathing, which can contribute to better throttle response and potential power gains when combined with other supporting modifications.
• Ideal for enthusiasts upgrading their engine internals for street performance or light track use.

Construction & Design:

The intake valves are crafted from high-quality materials with a chrome polish finish that not only improves durability but also reduces friction between the valve and valve guide. The slightly larger 36mm head diameter (+1mm) is designed to optimize airflow without compromising valve seat sealing or engine reliability. This careful balance of size and finish ensures that the valves maintain OEM-level reliability while offering a performance-oriented upgrade.

GSC Power Division’s attention to detail in manufacturing guarantees that these valves meet strict tolerances, ensuring smooth installation and consistent operation within the FA20 engine’s cylinder head.
