and the way the injectors are designed, 2 streams are aimed at each valve head. The older design aims at the port divider, which almost certainly causes some problems with fuel puddling. As for why it appears there are 3 streams in the pictures, it must be the angle at which they were taken. The new injectors have 4 holes...this I am certain of. The overal industry trend (aside from direct injection) is for more streams. The new injectors used on the VQ35 have TWELVE streams.
