with the high flowed throttle bodies can you order them interstate or most it be done at rpw, sorry if this is a dumb question.

Yes we do deliver COD Australia post interstate with exchange units.

so how much is it after exchange, $220? or less? as you can tell a lot of people are doing a bit of research into this,so sorry about the 100 questions

$220.00 for the modified throttle Body
$220.00 surety / core charge if an exchange unit is supplied which is refundable upon return of your origonal unit back to us.

Freight and handling charges vary according to location etc.
