Premium Sealing for Subaru EJ Engines

Maintain optimal engine health with the GSC Power Division Viton 6mm Valve Stem Seal Set. Specifically engineered for the Subaru EJ series engines, these seals provide excellent heat resistance and durability compared to factory rubber seals. They are an essential upgrade for any high-performance build or engine refresh.

Why Choose GSC Viton Seals?

  • Material: High-grade Viton material resists hardening and cracking under extreme heat.
  • Compatibility: Perfectly sized for 6mm valve stems found in Subaru EJ20 and EJ25 engines.
  • Fitment: Wide compatibility including WRX, STI, Impreza, and Saab 9-2X Aero.
  • Performance: Prevents oil leakage into the combustion chamber, reducing oil consumption and exhaust smoke.

The valve stem seals are often overlooked during engine builds, but they play a vital role in keeping your engine clean and efficient. As your Subaru ages, the original seals can become brittle, leading to oil blow-by. By installing these premium GSC Viton seals, you ensure that your valve train remains properly lubricated while keeping oil out of the cylinder. This set is compatible with a wide range of Subaru models from 1999 through 2015, making it a versatile solution for many enthusiasts. Upgrade your engine's reliability today with quality components from GGCRACING.
