Polini 360° Intake Manifold – PWK / VHST – Piaggio

High-performance intake manifold from Polini, designed for maximum flexibility and performance. It features a CNC-machined aluminum base plate combined with a high-quality Viton rubber intake, offering excellent durability and adaptability for various carburetor setups.

Thanks to its 360° rotatable design, the manifold allows full adjustment of position and angle, making it ideal for installing larger carburetors even in tight engine bays.

Suitable for a wide range of 2-stroke models (50cc–180cc) from Piaggio and Gilera, including Piaggio Zip, Piaggio Typhoon, Piaggio NRG, Gilera Runner, Gilera Stalker and Vespa LX.

The intake rubber is simply inserted into the aluminum base, ensuring a secure and reliable connection without the need for an additional gasket. The Viton material provides excellent resistance to heat, fuel, and vibrations, making it suitable even for high-performance racing engines. The design also improves vibration damping, contributing to better engine efficiency and performance.
