These are a plug and play wiring solution to run 1JZ VVTI injectors on your 1G (or any 1JZ replacement)
Stock injectors are limited under 200hp. With the 1JZ injector upgrade you can see as much as 350hp+ whilst retaining a budget OEM injector for drive-ability and reliability.
Made here in Sydney Australia using Tefzel M22759 milspec wire.
