silencieux filtre à air scoot débridé

thingiverse

When you remove the air filter from a Piaggio NRG, it becomes very loud. Adding this to the original and filling it with glass wool or cotton (not too packed) makes it much quieter. Printable without support, but better with support on the plate. Two holes for passing a bolt and nut to secure it to the air box. You can add a little hot glue or silicone to create a seal. It should fit many scooters, such as the Thypoon, Stalker, since they have the same boxes normally. Let me know if this works for you too, it will be great! You may have a detuner on the air box that sticks out (small plastic lip), cut it off. This is my 2nd model, I only installed the first one, but it needed a notch because of an ignition coil screw that blocked it, I redesigned them but didn't try, so the notch might still be a bit too small, a few cuts with a cutter will enlarge it. I also redesigned the cover, it may be a bit tight to fit, filed down with a cutter in the recess and some glue.
