I have my audi ABZ running on the stock injectors which have big, stupid air jackets and a lower gasket that is larger diamter than normal.
This means that the injector holes in the intake manifold are bigger.
What have people done to install bigger/better injectors and eliminate the air jackets without too much machining, etc?
EFI Express designed and manufactures something to take care of that:
