an arc airbox if f**king awesome dudes.
definaely worht the cash i spent getting mine. i have had a few different intake setups (stock airbox with upgraded panel filter, apexi pod on a 3 inch metal intake pipe etc) and the arc is the only one which u actually notice the difference over the whole rev range it is more responsive.
ive been pulled over many many times with it and never had a problem however petit is another story lol
