intake manifold 21mm unrestricted for Minarelli horizontal, CPI, for: Keeway, 1E40QMB IP10979 fitting for Motowell Magnet RS 50 2010, 5,3 PS, 3,9 kw

Very low-cost intake manifold for derestricting the inlet port. This increases the size of the opening to 21mm. This is a must when using a larger carburettor. Even when used with the original carb, acceleration is increased. A sensible purchase if your manifold shows signs of wear or becomes porous.

Carburetor Mounting dimension: 24mm
