Key Features

• Optimized Intake Passage: Engineered specifically for performance tuning. The optimized internal flow reduces air turbulence, allowing the engine to draw in the fuel-air mixture more efficiently for instant power gains.
• Superior Aluminum Construction: Unlike plastic or low-grade alloy manifolds, our precision-cast aluminum alloy offers exceptional durability and corrosion resistance, ensuring it won't warp or crack under high-stress racing conditions.
• Instant Throttle Response: The included high-response reed valves enable more complete combustion. After installation, you’ll experience a more responsive throttle and significantly stronger acceleration out of the corners.
• True Plug-and-Play Upgrade: Designed for a precise fitment that requires no complicated engine modifications. It’s a straightforward bolt-on part that saves you time and effort in the garage.
• Large 45mm Inlet: The generous 45mm (1.77") inlet diameter is perfect for pairing with larger racing carburetors to maximize the volumetric efficiency of your 50cc or 90cc engine.
