Piaggio Airbox mod

this is a airbox mod for piaggio scooters, it replaces the tube inside the airbox to let air flow more freely

-if its too loose you might want to use some glue to fix it in place
-performance-wise I saw a noticeable gain in power at low to mid rpm
-it is just a tiny bit louder
-note that my scooter is far from stock and I use a red malossi air filter, every scooter is different so results may vary
