I only have 3 sets left of injector quick release plugs. I just installed on my 1990 awd talon i recently got, it saved me alot of time. When i am swapping ecu's and injectors its real simple and easy. no need to worry about loosing those little metal clips from stock oem injector plugs. If your tuning and having to keep switching injectors then these will save you alot of hassle.
