Hey mate i sourced mine from nz they have heaps of them over there just gotta find one thats not to beatin up...
I paid $350AU for the intercooler $50AU for the guys trouble of boxin it up and $120AU postage and handling... Then i got a bonnet scoop off ebay $200AU plus $50AU postage and handing $770 all up and haven't had it fitted yet just started new job with less pay so might not be put on for a while if ever
hope tha helps or give you an idea of cost think i payed a bit extra for postage but both exellent condition and arrived safe.
