I didn't get charged for postage, they billed me for the injectors and sent an invoice for shipping but never charged me for it. Took 1 week to get here.
If the DW have the same spray pattern/nozzle, they come with injector flow tests and lets just assume that a local flow test also matches this then what is the issue?
They bolt in and look stock which no others do and they have the same spray pattern etc, if they flow identically then it seems they have two pros, cheaper, look stock over everything else and no cons?
I am really quite confused where you are coming from GT. How does the quality differ from bosch etc? What evidence do we have that there is any difference what so ever?
