Buddy. Bro. Pal. That filter is washable and reusable. Says it right on the box.

I would have made sides for the air filter with plenty of glue and made a rim like how it comes

That’s what I mean a diy air filter element better than the Chinese one that comes in the scooter

How to save money and dust your engine. Appears how you installed will allow dust past the sides. Not worth the risk to engine damage.

Amico, hai sbagliato tutto....lavoro pessimo
