Supertech Subaru EJ20/EJ25 Sodium Filled Inconel Exhaust Valves, Set of 8 - SEVI-1010-HS-8
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits Subaru EJ20 and EJ25 engines.
These Supertech Performance exhaust valves are specifically engineered for high-output turbocharged Subaru builds where exhaust gas temperatures (EGTs) reach critical levels. Manufactured from Inconel, a high-strength nickel-based superalloy, these valves maintain structural integrity under extreme thermal stress that would compromise standard stainless steel components.
The defining feature of the SEVI-1010-HS-8 series is the sodium-filled hollow stem. As the valve operates, the liquid sodium transfers heat away from the valve face and through the stem to the valve guide and cylinder head cooling jackets. This improved thermal management reduces the risk of pre-ignition and allows for more aggressive tuning in high-boost EJ20 and EJ25 applications.
- Material: Inconel Superalloy
- Design: Sodium-filled hollow stem for superior cooling
- Quantity: Set of 8 exhaust valves
- Manufacturer Part Number: SEVI-1010-HS-8
