ITG high flow filter onto a samco 90 degress elbow pipe is the best for my vts without a doubt

ive tryed k&n , pipercross viper , pipercorss cone and green cotton
I used to have a panel filter setup with a modded air feed that was ok but feelt restrictive
Just make sure you get a good cold air supply to the filter as when doing sub 40 mph u car will feel a tad boged down but get above 4,000 rpm and youll fly
best of all the setup cost me about 80 quid lol thats a itg filter and a samco induction hose
