Vespa 300 Tuning Airbox Air Filter GTS GTV HPE Supertech 125 250

3F Motorsport Tuning Airbox Front Shell for all Vespa 300, 250 and 125 models (not for Primavera and Sprint). Our front shell is modeled after the original part and fits Plug'N'Play into the corresponding Modern Vespa models.

Since the original part severely restricts airflow, we have developed a flow-optimized version. The air filter insert corresponds to the original, so any sports air filter can be used. The front shell is printed in two parts from high-quality ASA and is very solidly built (joined in the middle). It even weighs slightly more than the original, which speaks for its stability. The kit has been long-term tested over 5000km and has withstood all stresses.

Mapping is recommended to exploit the full potential of the airbox front shell. Only the front shell is sold.
