Brand new still in box, never opened. I’m usually pretty good with installing parts I purchase. But after seeing the install guide online this is a little more than I’m comfortable with.
I will ship for free in USA only, all others would need to cover shipping costs.

I'm curious how a spacer would add those kind of horsepower and torque numbers. Seems way optimistic to me. Can anyone elaborate?

It raises the rpm band and the spacer allows more air flow which is where the increases come from. I added a plenum spacer to my 03 Mach 1.

It’s really not that difficult. The hardest thing it create complete seal around all 18 runners and getting the torque bolts correct.

Not sure except it’s supposed to reduce air temperature and help minimize heat soak.

We have an 03 Mach 1. Do you still have yours? Our is Azure Blue. I bought it for my wife new for her 30th birthday.

This is the correct theory. I wouldn't believe the stated claims, though. The temperature of the air coming into the intake is a more dominant factor than any heat transmission between the head and intake. If that were the case all manifolds would be composite (some are, but not for this reason).

It will actually lower the rpm where the peaks occur, albeit slightly, due to the increased runner length. Tuning and runner length have an inverse relationship. Airflow will still be constrained by the head and intake runner geometry so I would not expect any increase due to this component alone unless the airflow makes a severe turn at the head, which is not the case with the 7.3L manifold.

No, Its been a long time. I sold it to purchase my first house. I ordered it in July 2002 and came in Jan 2003 DSG. Loved the Mach 1. However I have to say the 16 Fiesta ST I used to have was actually even more fun to drive.
 
16 Fiesta ST
Hijacking bigtime now, apologize! I had a SVT focus and the Fiesta ST feels very similar. I agree it is one of the most fun vehicles I have driven. Ok, its not the fastest thing, but it sure puts a smile on my face and I guess that is really all that matters at the end of the day.
 
I can't speak to this installation, but I tried something like this on my S197 and the results were imperceptible.
I ended up pulling it off and tearing out those emissions valves too, for the life of me I can't remember what they were called, it's been years.

I'll say that once the intake and the exhaust were unburdened by that EPA shit, the vehicle became more powerful and surprisingly more fuel efficient. I think, all told, that I added about 100 rwhp to the car, and I still daily drove it around 13mpg city.
