smoother throttle response and wuicker pick up.
but the standard paper filter with resonator removed is pretty good to but the viper has a deeper burble. its all down to perswonal preference but after experiencing both on different st170s i would choose the viper BUT only if coupled with better exhaust and a remap,
viper = more in exhaust = more air out its the oldest most basic first steps to tuning.
the standard paper filter actually flows better than a K&N panel
