Supertech Performance FIVN-2502D-8 Black Nitrided Intake Valve Ford EcoBoost Oversize - Set 2.0L 2.3L 1mm

These performance valves feature a +1.0mm oversize head diameter and sodium-filled construction for superior heat dissipation and engine reliability.

Key Features:

• Constructed from high-grade EV8 (21-4N) stainless steel for maximum strength and durability
• Proprietary black nitride coating provides harder surface with increased wear and corrosion resistance
• Oversize 33.5mm head diameter (+1.0mm) for improved airflow and performance
• Sodium-filled valve design for enhanced heat transfer and lower operating temperatures
• 5.47mm valve stem diameter with triple-groove design
• 103.3mm overall length for precise fitment
• Uses OEM valve locks/keepers for simplified installation
• Reduced friction coating improves valve motion efficiency and extends service life

The black nitride coating reduces friction and wear between valve components, leading to longer lifespan and potential power gains especially at higher RPMs. These valves are ideal for high-performance street builds, forced induction applications, and racing engines that demand superior reliability. Set includes 8 intake valves to service a complete 4-cylinder engine.

Note: Oversize valves require machining of cylinder head valve seats for proper installation. Professional installation recommended.
