Product Details
A video is worth a few thousand words. Watch the video below for a full kit description with up-close details and testing results. (The video shows the 4.5 injectors - everything is the SAME except the internal release mechanism.) IMPORTANT NOTE: Wire plugs are NOT included as shown in the video, but can be purchased separately. Many buyers choose to keep with their original plugs.
This month's bonus: We will include a set of modern plug in wire connectors at NO CHARGE with your order now. You do not need to use these plugs. The original plugs will work if they are not damaged. You would need to splice these into your wiring with butt connectors ( either wire can go to either side of the injector plug. There is no polarity). So it will be your choice whether or not to use them. They are free!
