Subaru BRZ Intake Valves - GSC Power Division - Chrome Polish +1mm (2014+). 21-4N stainless intake valves for FA20 engines with a chrome-polished finish and +1 mm head diameter.

For Subaru BRZ, Scion FR-S, and Toyota 86, these 36 mm (+1 mm over stock) valves are precision machined for durability, heat resistance, and consistent sealing at higher rpm. The chrome-polished stems reduce friction and guide wear for stable valvetrain motion. Oversize heads support performance head builds and may improve flow when paired with proper seat machining and tuning.
