Scion FRS Exhaust Valve (1) by GSC Power Division, +1mm Chrome Polish 30mm Head. For FA20 FR-S/BRZ/86 (2014+), this oversize valve adds precise, durable performance.

With a 30mm head that is +1mm over stock, it increases curtain area for builds with cams or head work. The chrome-polished stem reduces friction and helps resist carbon, and tight tolerances support reliable sealing under heat and RPM. Direct fit for FA20 heads, GSC PN 23-8N, and sold individually—ideal for refreshes or performance rebuilds.
