On the wee golf mk4 1.4 16v it has orange tabs. I then see another golf same spec with red tabs on the injectors? Why? I know the 1.6 is blue
dont always go by the tab colour though its usually a good indication, ideally check the part number on the injector. (there are 2 orange tab in a list I have handy, ford KA and VW 1.4 16v for example) these are usually magneti marelli make injectors and have a simple code system on the side you can use to look them up IWP xxx so for example heres a couple which may be relevant to your interests: IWP 025 - 200cc/min - (yellow) Polo 1.4/1.6 16v 036906031A IWP 031 - 200cc/min? - (blue) Polo 1.4/1.6 16v 036906031A IWP 092 - 131cc/min - (orange) Polo 1.4 16v 75bhp 036906031g
036 031Q on my blue injectors, with different numbers on the same injectors. 244900 244900 245900 243900
IWP 058 are off a 1.4 16v, cant find any data on those either I'd assume the 1.6 ones would flow more, but wont be 'better' unless the ecu is matched to them
