High-Flow Intake Valve for Briggs World Formula Performance

Breathing deeply wins races—the Intake Valve (SKU 557017) opens wide to flood your World Formula cylinders with air. Its dished profile streamlines flow paths, reducing restrictions that hinder rev buildup and power onset.

Feel the surge as fresh charge packs in denser, igniting more forcefully for that instant punch off the line. In technical tracks, precise intake timing means better velocity through esses, where others falter. This valve's material resists warping, maintaining seat contact for leak-free operation lap after lap.

• Optimized angle for maximum port utilization
• Lightweight stem minimizes inertia
• Pairs with dual springs for high-RPM control
• Enhances fuel atomization for cleaner burns

For the organized mechanic, it's a straightforward swap during valve jobs, keeping your schedule tight. SKU 557017 isn't just replacement—it's an upgrade to valvetrain harmony that translates to faster, more agile karting. Harness it to outpace rivals with superior volumetric efficiency.

Beyond specs, consider endurance: it handles heat cycles without fatigue, supporting aggressive cam profiles. Racers tuning for specific classes find it versatile, adapting to mods that push boundaries while staying compliant.
