What injectors are these , I have this brand new set of 8 that came with my car.

 

they are multecs. regarded around here and injector specialists (such as Crzuin Performance)as the worst injector designed. in this design gas is used to cool the injector coils. unfortuanately the same gas that cools the injector coil windings, eats the protective coating on the windings. this in effect causes the injector coil to short and fail.

 

Thanks. Lots of info on the board with a search now that I know the name
