Rubber boot that covers the alternator wires coming out of the crankcases on Ducati 250/350/450cc W/C singles. This boot fits over the gland nut on top of the engine cases and keeps things looking good. Boot has a ID of 28mm and 30mm tall. The hole for wires is 8mm and Ducati part number 0609.46.060
NOTE: These are a really tight fit and need to be stretched a lot to fit. All Italian suppliers use the same too tight size that's very hard to install.
