i have a friend who is wondering if his injectors are stock or aftermarket.i told him honestly i'm not really sure if and how you would know by looking.does anybody know?thanks.

 

Im not really to sure how to tell yourself, im not sure if theyll say bosch or anything stamped on them.. probably not i dont remember. If they have any type of number call bosch with that number. But other than that take them to some place that deals with injectors they can measure them. Any place that hones them out can tell you too. Scheiddiesel will hone them if you send them in. They would probably tell you how big they are if you sent them to them, but then again your going to have to pay shipping.

 

the nozzle will have a certain amount of orofices, i'm not sure how many but wen i changed mine that was the only difference i could notice between the stocks and my 370 marines
