There are two ways to do an exchange. You can send your old turbocharger first. We will dispatch your reconditioned turbocharger as soon as we receive an old unit. If you would like to receive turbocharger before returning your old unit then we must collect a fully refundable surcharge for EACH turbocharger. As soon as we receive an old unit we will fully refund your deposit. We collect surcharges via PayPal.
