Supertech Black Nitrided Intake Valve Set of 8 for Subaru EJ20/EJ25 - SIVN-1010-8
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.
This set of 8 Supertech intake valves is engineered for high-performance Subaru EJ-series builds that demand superior valvetrain durability. Each valve is manufactured from one-piece forged stainless steel and undergoes a specialized black nitriding process. This treatment creates a high surface hardness and a smooth finish, significantly reducing friction within the valve guide while improving resistance to wear and heat-cycling fatigue.
Designed to withstand the stresses of increased boost and higher RPM ranges, these valves are a direct upgrade for performance-oriented EJ20 and EJ25 cylinder heads. The micro-polished stems ensure minimal parasitic drag and consistent operation under extreme thermal loads.
- Manufacturer Part Number: SIVN-1010-8
- Finish: Black Nitrided coating for reduced friction and increased hardness
- Construction: One-piece forged stainless steel
- Valve Type: Intake
- Quantity: Set of 8
- Fitment: Subaru EJ20 / EJ25 engines
