Has anyone tried a free flow panel filter on a 35iS like an ITG / K&N / Pipercross ?
I am just talking panel filter replacement ... nothing else. With the increased boost of the iS I wondered if it may actually make a difference worth the expense ? I usually don't bother with such things but as the iS is touted as having improved breathing over the 35i I was surprised to see the airbox and airfilter + the connecting pipes all have the same part numbers.
