1) Can i install the h22 skunk2 Intake Manifold in a 4th gen with the IACV bolted to the back or do i need the relocator?
I called skunk and they said the h22 in a prelude 4th or 5th gen doesn't need the IACV relocated , but civic and other chassis do.
Can someone confirm this

2) Do i need 3 washers for the studs that go between the fuel rail and intake manifold?

3) If I use the skunk2 manifold with an s300 with a p72 can i just unplug and cap off the vacuum line going into the EGR piece that bolted to the original manifold without throwing a code? I believe the p72 doesn't read EGR and i think i can disable it anyway with the hondata.
I found out from my tuner since the p72 and p28 don't ready EGR you can unplug and cap off vacuum. the skunk2 manifold or hondata IM gasket will block the EGR on the manifold side.

 

1. Not sure about the 4th gen but there is no room in my 5th gen, had to use the relocator. The install instructions that came with my manifold had pics of a 4th gen and the pics showed the relocated IACV.

2. Use the original spacers off the rail.
