    This is a DiTech-section. But with that kind of setup I would use the stock filter.

    i wouldn't say anything under 70cc i would just say that if the scooter is still stock it doesn't bring you any performance or at least almost none... but if you want your scooter to sound alot more 'beautiful' to the ears of the population go ahead you will only need to check what your stock jet is and buy another jet that is about 5 higher... for example if your jet is 80 get one that is 85

    There's nothing under 70cc that will make GOOD use off a pod filter or similar... The speed difference you will get will be so minimal as it will only be from the lesser amount off money in your wallet due too the extra fuel you use.

    I put a cone filter on mine a while ago. In my opinion it does add a bit of kick in the accelleration. But the throttle response is a bit odd and takes some getting used to. Make sure you secure it on well. Mine fell off so i attached it with some cable ties to the old airbox bracket then it got nicked. Maybe put the new filter on and leave the metal airflow restrictor on?

    it does lower your MPG's but it is so minimal that he will not really notice it....
