GSC Viton Valve Stem Seals (6mm, Set/16), 2002-2014 WRX & 2004-2021 STi

GSC Power-Division Viton Valve Stem Seals use genuine DuPont Viton fluoroelastomer material. Viton was specifically developed for the extreme conditions seen in today's high horsepower, sport compact engines. Held to a higher standard, GSC Power-Division Viton valve seals provide improved resistance to high temperatures, fuel, and chemical contaminants as well as extended wear as seen in high rpm or high mileage engines. GSC Power-Division doesn't believe in cutting corners, that's why the Viton valve seal kits are used on both the intake and exhaust valve seals. All of this performance for a fraction of OEM dealership parts, GSC's Viton valve seals are perfect for all situations.
