2015-2021 Subaru WRX

Optimize your Subaru WRX engine’s reliability with this premium set of Viton valve stem seals from GSC Power-Division. These seals are crafted from high-temperature fluoroelastomer material to withstand the added heat and stress that comes with performance driving. Sold as a complete set of 16 (intake & exhaust), this upgrade is ideal when performing a valvetrain overhaul, installing aftermarket springs, or simply replacing aging OEM seals.

Key Features:

  • High-Temperature Viton Material: Engineered to cope with elevated engine bay and combustion temperatures, providing longer service life than standard seals.

  • Full Engine Set (16 Seals): Includes both intake and exhaust stem seals for all cylinders—one-stop solution for rebuilds or upgrades.

  • Performance-Ready Upgrade: Ideal when using high-rev, turbo, or track-oriented builds where reliable sealing and low oil consumption matter.

  • Improved Sealing Performance: Better resistance to heat, oil, and wear helps prevent blow-by, oil burning past seals, and ensures smoother engine behavior.

Over time and under performance conditions, factory valve stem seals can harden, crack, or leak—leading to oil entering the combustion chamber, increased emissions, and potential power loss. Replacing them with high-performance Viton seals secures the integrity of the valvetrain, supports longer service intervals, and gives you peace of mind as you push your FA/FB engine build.
