i have fitted a simple cone filter. removed the standerd box, made some holes in the wheel arch liner, re-located horn to the bolt hole the old air box bolted to, ran a big **** induction pipe down to the vent were the spot lights are. to get round the hot air being sucked in, i removed the heat-shield that was attached to the standerd air box, reshaped it so it kinda curved round the cone filter (leaving about a 2" gap between filter and H/sheild) and i now have a nice filthy sounding spooling sound, hissisng when the boost gets up and a nice medium volume flutter when i change gear!! works fine, sounds good, looks pretty cool too!! ill bang a pic up later!
