intake manifold 21mm unrestricted for Piaggio 2-stroke IP12456 fitting for Aprilia SR Ditech Street 50 TE000 2005, 5,4 PS, 4 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.
