Check out my custom intake manifold (MSP) Been working on this thing for a while now, finally almost done with it. Pics first... And here is the plenum floor plate / velocity stacks: Car is a Mazdaspeed Protege with a .86 GT28RS. Nobody makes an intake manifold for us, so I decided to give it a shot. Still need to put the fuel rail mounts on it, but other than that it is ready. We'll see what kind of power it actually makes later this week. OT's thoughts?
