Malossi Manifold D 20x25 straight in rubber for PHBG 19/20 carburetors

The Malossi intake manifold Ø 20x25 is an essential component for the engine, allowing the entry of the air-fuel mixture into the combustion chamber. Thanks to its intelligent design, it offers numerous advantages and features that improve the overall performance of the engine.

One of the main advantages of this manifold is its high volumetric efficiency. This indicates the ability to introduce a large amount of mixture into the combustion chamber compared to the engine displacement. The manifold is designed to minimize friction losses, ensuring a smooth and unobstructed flow from the air intake to the combustion chamber. This results in better engine performance and increased power.

In addition, the intake manifold also serves as a fresh charge accumulator. When the reed valve closes, the mixture accumulates in the manifold, compressing against the reeds. This allows for a fresh charge ready to be used when needed, improving engine responsiveness and power delivery.

In addition to improving engine performance, the Malossi intake manifold also provides a solid connection between the carburetor and the engine. This prevents vibrations that could cause fuel and air emulsion in the carburetor float bowl, ensuring optimal operation and efficient combustion.

Malossi, with its extensive experience in the field of engine fuel systems, has developed a line of rubber and aluminum alloy manifolds specifically for the latest generation scooters. These manifolds have been tested and developed by the Malossi research department, both on the road and on race circuits, to ensure excellent performance in every situation.

The composite structure of the Malossi rubber manifolds, with an aluminum insert embedded in a material resistant to oils and gasoline, provides a solid mounting base and good elasticity of the manifold body. This ensures long-lasting durability and perfect adaptability to the engine.
