GSC P-D 2014+ Subaru/Scion BRZ/FRS FA20 21-4N Chrome Polished Intake Valve 35mm STD - 8 QTY (2132-8)
In the pursuit of engineering excellence, our mission was clear — to develop a valve line that stands as a benchmark for performance and durability within the aftermarket. Armed with cutting-edge 3D design and simulation software, we embarked on crafting a valve head design that not only excels in strength but also enhances the overall flow dynamics. Each valve head is a testament to our commitment to perfection. We subjected prototype valve heads to rigorous flow tests, ensuring that the final design stands as the epitome of high-flow capability within the current market. The materials selected for construction play a pivotal role in minimizing valve distortion at the face, surpassing the performance of all tested designs. This reduced distortion is more than a design feature; it's a strategic choice that pays dividends in challenging conditions. The result is superior sealing under extreme circumstances, providing unmatched consistency throughout the valve's lifespan. We are proud to introduce GSC Power-Division's new valves, poised to set a new standard for sport compact performance valves in the automotive industry.

APPLICATIONS
- Subaru/Scion BRZ/FRS FA20 (2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023)
FEATURES
- Swirl polished heads for smoother air flow over the valve
- Back cut to reduce valve weight for higher RPM, higher boost pressure, and allow for more aggressive cam profiles without increasing valve spring seat pressures
- Valve stems are micro-polished to allow for less oil retention on the stem, which creates less drag on the stem to guide for a smoother motion
- Intake valves are a modified 21-4n stainless and exhausts are a modified 23-8n stainless material for high heat capacity while maintaining longevity
- Valve tips are either hardened or have a stelite wafer tip fused so that the tip is within 5 Rockwell C of the rocker or valve tappet for extended life and less wear
- Valve tip lengths - we have taken extra time to adjust tip heights on the applications to require less tipping of the valve, to maintain proper tip height for proper valve train geometry, and to cut down on install times when setting valve lash
- We have also adjusted the keeper groove to properly balance intake and exhaust spring pressures to reduce the use of valve spring shims and maximize performance from our spring and retainer kits
- Valves will work with an OEM keeper/lock or, when available, our upgraded keeper/lock. It is not mandatory, but it is suggested, that any valve lock not be reused on performance applications due to material grooving
