The little support bracket that comes with the intake should go on last. With it removed, it will give you enough clearance to get to the bolt. I had to use a 1/4" drive ratchet with a short handle and a deep socket. That gave me enough clearance to tighten the bolt up. This is definitely a bolt you need to get to from underneath the car.
The PS pressure sensor you can twist a little to give you the clearance to bolt the mani up.
Didn't you get a dipstick with your intake mani? Mine installed fairly easily. The dip stick bracket didn't line up perfectly though. I just had to bend the dip stick a little for it to line up.
No I don't think my car needs "moar low". I apologize to everyone for my car not looking like all the other Foci at FR14.
