Shane, the little holes not the larger ones. Besides the injector holes are on the opposite side, talking about the real small holes above the intake port.

sorry I did not see them until I enlarged the picture just now. what year and model civic do you have?


2000 Civic EX 1.6 V-tec.

so you have the d16y8 engine I have a stock y8 manifold in the garage and it doesnt have those holes. I have seen some after market ones that have extra holes for nitrous and such. but honestly I am at a loss for what the holes are for as of right now but I am gonna keep looking into it
