Is your GY6 scooter suffering from rough idling, hard starting, or poor acceleration? A cracked or warped intake manifold is often the culprit. This direct-fit replacement intake manifold pipe restores proper air-fuel mixture and eliminates vacuum leaks, bringing your 125cc or 150cc scooter back to peak performance.

Key Features

• Exact Fit for GY6 Engines – Designed specifically for 125cc (152QMI) and 150cc (157QMJ) GY6 4-stroke engines. Also compatible with many 50cc GY6 variants and popular Chinese scooters, ATVs, and go-karts from TaoTao, Roketa, Jonway, Lance, and others.

• Durable Construction – Made from high-quality rubber bonded to a metal flange, resisting cracking from heat and ethanol-blended fuels. Performance cast aluminum options are available for upgraded carburetors.

• Plug-and-Play Installation – Includes the manifold, intake gasket, and mounting clamps. Simple bolt-on replacement – no modification required. Clean the mounting surface, install the new gasket, and torque to spec.

Why Replace Your Intake Manifold?

Old intake manifolds often develop cracks or warped flanges, leading to:

• Vacuum leaks and erratic idle

• Lean fuel mixture causing overheating

• Hard cold starts and hesitation on throttle

• Reduced fuel economy and failed emissions

Installing this replacement restores proper sealing, ensures correct air-fuel ratio, and improves throttle response.

Installation Tips

• Always replace the intake gasket (sold with most kits).

• Apply a thin layer of high-temp sealant for an airtight fit.

• Cap any unused vacuum ports.

• After installation, spray carb cleaner around the manifold – an RPM change indicates a leak.
