The different thicknesses of the washers will effectively move the nozzle up or down and change how the injector sprays in relation to the piston bowl. For example, if you use too thick of a washer, the injector will sit higher, potentially spraying fuel out of the bowl.

haha they are awsome. i am very happy with them. smoke isnt out of control. egts are nice and low. i never got those stickers tho . once i get the money for a better fuel pin and a electic fuel pump i should have a good setup. once the new year rolls around i think my father might be lookin your way for some business with injectors and stuff.
