Nitrided Exhaust Valve for Durable World Formula Engines

Exhaust flow dictates recovery speed, and the Nitrided Exhaust Valve (SKU 557018) excels at purging spent gases from your World Formula engine. The nitriding process hardens the surface against scorching temps, ensuring it seals tight even after hundreds of heat cycles.

• Enhanced durability for prolonged valve life
• Streamlined head for reduced backpressure
• Compatible with racing manifolds
• Boosts volumetric efficiency on exhaust stroke

In the roar of a straightaway, this valve snaps open to evacuate chambers swiftly, prepping for the next intake with minimal overlap loss. Result? Quicker revs and a broader powerband that keeps you glued to the leader. For trackside pros, its robustness means fewer teardowns, organizing your season around wins, not wrenching.

Compared to standard valves, SKU 557018's treatment resists recession, maintaining timing accuracy that sharpens overall performance. Integrate it into rebuilds for a valvetrain that endures the grind of weekly races, delivering consistent speed you can count on. It's the detail that fuels championship drives.

Technically, the nitriding penetrates deep, forming a tough layer that fights erosion from hot exhaust streams. Paired with sodium-filled stems in advanced builds, it cools efficiently, preventing hot spots. Kart teams leveraging this valve report smoother power curves, turning potential weak links into strengths.
