For the Vaccume ports, just use what you need, and cap off the rest.

one problem..... boost
won't they just blow off

#1 is for a coolant deal. not quite sure of it's purpose. it looks like a cylinder. you might be able to see it in a pic in my cardomain deal.

#2 i'm not sure of. does it actually go into the runner?

#3/4 are vacuum ports. you'll be surprised that you can use them all. boost gauge, bov, boost reference, etc.

#2 is nothing, a plate screws into there that has a 90 degree bend and is used like a washer on the bolt that screws the Intake Manifold to the engine head. It has no use really.

Does the gtx manifold bolts onto the protege lx 1.8L engine?

I put vac caps on the ports I didnt use and then used really small zip ties to secure them on.
