GSC P-D Subaru/Scion FA20 BRZ/FRS/FT86 2014+ 21-4N Chrome Polished Intake Valve 35mm STD - 1 QTY (2132-01)
Our goal in developing our new valve line was to produce the highest-performing, longest-lasting valves the aftermarket could offer. Through the use of sophisticated 3D design and simulation software, we have developed a valve head design that is stronger and flows higher. To ensure that we have the highest flowing valve head on the market right now, we flow-test prototype valve heads in the relevant applications. We have less valve distortion at the face with the materials than with any of the tested designs. Reduced distortion enables more reliable performance throughout the valve's life and better sealing in adverse situations. The new valves from GSC Power-Division are certain to set the bar for sport compact performance valves in the industry.
SPECIAL NOTE: 2014+ Model Fitment ONLY
Applications
- Subaru/Scion BRZ/FRS (2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021)
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
