Reed Valve Block as connection between Intake Manifold and engine block - controls the intake process in the diaphragm system.

The Reed Valve Block connects the Intake Manifold and engine block and controls the intake process. Due to the flow-optimized passage, racing diaphragm blocks are among the basics in engine tuning, which is why a wide selection of original and tuning blocks is available for common diaphragm systems. Reed Valve Petals as well as the Reed Valve Block (for Casing and Twin Intake) are available separately for the POLINI Reed Valve - ideal as a replacement if the original block is damaged or worn.

Conclusion: Provides the right vibrations.
