Description

Upgrade your Subaru WRX or WRX STI engine with the GSC Power-Division Viton Valve Stem Seals, designed for models from 2002-2014 WRX and 2004-2021 STI. These premium seals provide superior heat resistance, helping to maintain optimal engine performance under high temperatures common in high-performance builds. Perfect for engine rebuilds or head assembly, they ensure reliable sealing and reduce oil leaks.

This set includes sixteen 6mm valve stem seals—eight for intake and eight for exhaust—crafted from durable Viton material. Viton’s heat tolerance makes these seals ideal for turbocharged Subaru engines, where temperature extremes can degrade standard seals quickly.
