Unlock more power from your Subaru BRZ or Scion FR-S with the GSC Power Division 30mm (+1mm) Exhaust Valve set. By increasing the valve diameter by 1mm over the factory size, these valves allow for improved exhaust gas evacuation, which is critical for high-horsepower builds. These valves are the ideal choice for those looking to maximize the efficiency of their cylinder head porting work.
The +1mm oversized design is specifically engineered to complement aggressive camshaft profiles and ported cylinder heads. The chrome polished finish reduces surface friction, allowing for smoother exhaust flow and less carbon buildup. These valves are built to withstand the increased thermal load of high-performance engines, ensuring your build remains reliable under pressure. When combined with proper tuning and supporting modifications, these valves will help your FA20 engine achieve significant gains in both power and throttle response. Upgrade your valvetrain with confidence using GSC Power Division components available through GGCRACING.
