If you can't figure it out this is the hf/std manifold
I have walked through the junkyard a couple times now and have not been able to find one of these. Were the cars that come with this style of manifold not made in Canada or am I just short on luck lol i'm pretty sure they come on 88-91 civic and crx's. Which engines are they found on? I saw a comment that they come on the cars with the 4 speeds??
