Helloow !!! Sorry I have a question, does it affect if I change the engine injectors 2.5 from cougar 00 to a ford contour engine 2.5 95 96 97? Does it affect the impedance of the injectors? No damage to the ECU?

Just use EV6 injectors, they're all the same, and are the only ones that fit your fuel rail correctly. In a return style car (most Contour/Mystiques and early 99 Cougars), EV1 injectors should be used. Do not try to mix the two because, as Andy said, they use different harness connectors. So to answer your question, pencil injectors, because they actually work in our application.

If you must, you can take the connectors off of an EV1 harness and solder them to an EV6 harness, allowing you to use EV1 injectors without harm to the ECU. You may wish to do this if you can't find a source of EV6 19#/hr injectors from a CSVT, but would still require either a reflash or an SVT ECU (which would have to XGT1) for the higher fuel flow.
