Eliminate intake restrictions and improve throttle response with the NCY Performance Intake Manifold.
Engineered for Genuine 50cc and 110cc two-stroke engines,
this manifold features a smooth-bore internal design and a specialized PTFE (
Teflon) coating to reduce intake turbulence and prevent fuel pooling.
It is the essential foundation for any “Big Carb” or cylinder kit upgrade.
Technical Performance Features
PTFE Low-Friction Coating: The interior and exterior are coated in high-durability Teflon to ensure maximum air velocity and resist heat soak from the engine case.
Versatile Carburetor Fitment: Designed as a direct bolt-on for aftermarket carburetors with a 33mm mounting flange (typically 24mm to 30mm bore sizes).
Integrated Vacuum & EGR Ports: Features dual ports (2.4mm ID) to maintain full compatibility with factory emissions and vacuum-operated fuel petcocks.
Complete Hardware Kit: Includes stainless steel Allen bolts and high-tension clamps to ensure a leak-free, high-pressure seal.
