These adapters allow you to use injectors having newer USCAR connectors (Bosch EV14 style) on older cars equipped with EV1 Minitimer connectors (square Bosch).

Use these adapters to run Bosch 550cc (EV14) injectors on your VW/Audi (MK3 ABA or VR6, MK4 1.8T or 12V VR6, B5 A4 1.8T, B6 A4 1.8T, B5 S4 2.7T, C5 A6 2.7T)

Should fit many other cars that use a regular square Bosch plug.
