havnet changed for a K&N filter. Are you talking about a straight swap for the filter in it now or changing the whole system for a pod? I would like to change the whole system to get an even better induction sound but dont know whats a good buy money wise. I did see the one floating around the forums that is about $600 and is a remake of an FPV v8 with an open vent. looks good. would love to catch up with someone who doesnt mind lending me one for like 5 mins to drive around in to see if I like it
