Additional air filter for the frame hole on Vespa Largeframe with SI carburetor
Additional air filter in the frame hole SIL-TECH PERFORMANCE Vespa PX80-200 and Largeframe Oldies with SI carburetor.
If a Venturi intake funnel is fitted to Largeframe Vespas, the standard air filter is no longer required. The tuning supplier SIL-TECH from Italy now offers an additional air filter for the frame hole on the Largeframe models so that the intake hose can still be used. This results in a significantly quieter intake noise with a retained filter function.
The filter element must be dismantled for installation (3mm hexagon socket required!), the seat and tank must be removed, then the oval filter housing is inserted into the frame intake hose opening, the intake hose is refitted - done! The inserted filter element can be removed for cleaning by unscrewing just two of the six hexagon socket screws. English/Italian installation instructions are included with the filter.
