Supertech Performance FEVI-2501F-HS Sodium Filled Inconel Exhaust Valve

The Supertech Performance FEVI-2501F-HS is a high-performance sodium filled exhaust valve engineered specifically for Ford EcoBoost 2.0L and 2.3L engines, as well as Ford Duratec and Mazda MZR applications. Constructed from premium Inconel/Nimonic alloy material, this valve is designed to withstand the extreme exhaust gas temperatures generated by modern turbocharged engines.

Advanced Sodium Filled Technology:

The sodium filling inside the valve stem provides superior heat dissipation, significantly reducing valve head temperatures compared to conventional valves. This thermal management improves material strength and durability while allowing tuners greater flexibility with spark timing advances. The result is a valve that runs approximately 10% lighter than OEM alternatives while maintaining exceptional reliability under high-boost conditions.

Premium Construction Features:

• Material: Inconel/Nimonic alloy for maximum temperature resistance
• Head diameter: 30mm (standard size)
• Stem diameter: 5.45mm
• Overall length: 104.7mm
• Single groove stem design for enhanced valve stem protection
• One-piece forged construction for superior strength
• Precision CNC machined to exact specifications

Performance Benefits:

Ideal for drag racing, rally, road racing, and high-performance street applications, this Inconel exhaust valve delivers cooler operating temperatures, improved durability under extreme conditions, and reduced weight for higher RPM capability. The single groove design restricts excessive valve rotation and extends valve stem life compared to factory multi-groove designs. Recommended for use with upgraded valve springs and valve stem seals to maximize performance.

Sold as a single valve. Ford EcoBoost 2.0L/2.3L engines require 8 exhaust valves for a complete set.
