Snorkels/flaps/new ecu/remap/extra parts to fit etc So me being a simpleton would like to ask.....can I just but a Karbonious and stick it in the car!!.....I'm thinking a remap is needed but is it essential? Also what other parts or mods are required... And what is this snorkel and flap thing......is it additional to the airbox and why would I need it ? I'm simply after a better induction sound and if there's some performance bebefit that will be a bonus Also how much do the remaps cost?....please give me an idea !!
