Unrestricted Airflow: NCY 30mm Coated Intake Manifold

Maximize the volumetric efficiency of your intake, ensuring better cylinder filling with the NCY 30mm Coated Intake Manifold. Standard rubber and cast manifolds often feature rough internal surfaces that create power-robbing turbulence. NCY solves this with a PTFE internal coating and a mirror-smooth bore, allowing a higher volume of air and fuel to reach your cylinder with zero resistance.

The Performance Advantage

• PTFE Coated Bore: The specialized coating provides an ultra-low friction surface, significantly reducing airflow turbulence compared to stock cast-iron or rubber intakes.
• Increased 30mm Diameter: Engineered specifically to support larger carburetors. Installing a 28mm or 30mm carb on a stock manifold creates a "lip" that kills velocity; this manifold provides a seamless transition.
• Vacuum Ports: Features a dedicated vacuum port, making it a "plug-and-play" replacement for modern street-legal GY6 engines.
• Heat Dissipation: The high-grade cast aluminum construction sheds heat faster than plastic or rubber, keeping your intake charge cooler and denser for better combustion.

Comprehensive Fitment & Compatibility

This manifold is designed for 125cc to 232cc GY6 (157QMJ/152QMI)engines and is a required upgrade for larger carburetors:
