Pulse adrenaline air filter

Hi there
Any sport air filter out there for pulse adrenaline 125

keep the box on, going to a cone airfilter or k&n typre is essentialy downgrading, the box stops crap/rain getting thorugh and into yur carb and messing the fuel system up, if you stick a "sport air filter" on youll have to rejet and its not worth it,
