Well, yes and no is the answer. Obviously they don’t make huge differences either way, but you should wait until the time is right to fit one.

The standard Air box is setup to work perfectly with your standard engine and exhaust so doesn’t need changing for a Malossi open filter. Adding a Giannelli race pipe makes the engine more efficient (throwing extra fuel make into the cylinder that’s normally lost out the exhaust) and also rev higher, so it is using slightly more air, but not enough to warrant changing the to a Malossi filter yet.

Adding a Malossi 70cc kit however, and things change; there is a 40% capacity increase there, so it’s obviously going to benefit from the greater airflow the Malossi air filter gives. Does it make a big difference though?

No, not really. It’ll improve the low down punch more than anything, but not real differences apart from it sounding better

The important thing to remember is to UPJET when fitting one; otherwise it’ll run lean and cause a seizure. I normally go up by 6 sizes or so depending on the model, and don’t fit one until I’ve got a Giannelli exhaust and Malossi 70cc kit fitted either, as a lot of models won’t run properly otherwise.

The other thing to consider is with British weather especially, it tends to rain a lot and an open Malossi air filter is going to get wet, then your scooter won’t tune very well at all. I know you can get open air filters with a cover on, but with half of them covered up, they don’t offer any air flow advantages really.
