conic Grade A – perfect repair Product description Bolt for air-filter of T5 carburettor Piaggio does no longer supply the relevant spare parts. Unfortunately this is true for a number of items for many models. As a result there often is one small part missing to keep the scooter on the road. At we do our best to remedy that problem. The Vespa T5 uses a larger air-filter and a suitable carburettor box cover, both unique to the T5 and not used on any other Vespa. As a result the standard PX bolts do not fit. It you decide to use them regardless they often work themselves loose to drop into the inlet tract, often with massive damage to the engine as a result. Absolutely make sure you use the correct bolts! TIP: The larger air-filter of the T5, with its integrated venturi, and the T5 carburettor are often used as upgrades on other P-Range engines. Do make sure you use the correct bolts there too. OEM numbers (for comparisons): S.15787 (PIAGGIO)
