The intake area of the SHB carburettor series from Dell'Orto is anything but streamlined at the factory for cost reasons. Tuned engines with SHB carburettors therefore benefit greatly from an improvement in this area.
The SIL Tech Performance intake funnel optimizes the gas flow. Powerful cylinders generate very high flow rates in conjunction with the small SHB carburetors. This is exactly where the SIL-Tech Performance intake funnel comes in. It ensures that the air can flow into the venturi area of the carburetor in a controlled and bundled manner without forming wake vortices.
The result is improved performance across the entire rev range.
An installation instruction is enclosed to the intake funnel.
