Supertech Subaru EJ20/EJ25 Sodium-Filled Inconel Exhaust Valve - +1mm Oversize - Set of 8

Description

Upgrade your engine with Supertech Inconel Sodium-Filled Exhaust Valves. SEVI-1014-HS-8 fits the Subaru EJ20/EJ25 Sodium Filled and is sold as a 8-pack.

Supertech Inconel Sodium-Filled Exhaust Valves combine the extreme heat and corrosion resistance of Inconel 751 nickel alloy with a sodium-filled hollow stem. The sodium inside the stem vaporizes under heat and transfers thermal energy away from the valve head into the stem and guide, dramatically reducing valve head temperatures in high-output applications. This makes them the preferred choice for high-boost forced induction builds and endurance race engines where conventional valves fail.

Supertech Inconel Sodium-Filled Exhaust Valve Features:

• 1-piece forged construction for maximum strength
• Premium Inconel 751 nickel alloy base material
• Sodium-filled hollow stem for active valve head cooling
• Dramatically reduces valve head operating temperatures
• Ideal for high-boost forced induction and endurance race applications
• Strict dimensional tolerances for direct OE replacement fitment
