10 throttle bodies, 16 intake tubes. Manifold porn doesn’t get much better if you ask me. If only the outside of the car looked this good.

What vehicle is this for

Mk VIII lincoln.

Not mine pictured, mines silvery blue and I haven’t taken any pictures of it not in the garage.

It’s what’s INSIDE that counts!

Mmmmm, sweet, buttery intake manifold.

Holy shit. This is gold. Delicious gold.

I get the 16 intake runners...10 TBs? How?

Well there’s the main TB which has 2. Only one opens until about half throttle, then the other opens up.

Then there’s the lower manifold aka IMRC. There’s a throttle for every other intake valve. The reason for this is dohc tends to lose torque, having the second valves shut on each cylinder allows the charge of the air entering during low rpm to be of a higher velocity. Giving the low end torque of a sohc, and the top end of dohc. These are controlled by vacuum on the earlier models (mine) and by computers in the later.

Thats really intresting actually.

I’d have to agree. Ford did a really good job on this engine. Probably why Koenigsegg uses it (FI) for their own cars.

The butterflies in the intake change the length of the intake for better output at lower rpm (longer intake runner) and higher rpm (shorter runner) than a one length intake runner. SOHC or DOHC has nothing to do with it. The shapes of the cam lobes not the number of cams will determine engine characteristics. Also it’s one throttle with two butterflies

I love that they showed off the runners through the engine cover. I miss my ‘93 sometimes.

Strictly speaking, it’s a two-barrel throttle body and 8 tumble-flaps.

The 8 “lower” throttles are actually tumble flaps (or swirl flaps on diesel engines).
The Audi website has a good explanation on how it works:

Mines 93 too. Best year by far. Still deciding if I’ll flip it when it’s done or play with it for a while.

Oh I see the air suspension has failed.

I can’t speak for randoms on the Internet but mine is now converted to static. All thunderbird suspension parts are compatible so lowering one the right way isn’t really difficult or expensive.

As far as the first part I have to disagree. If one port is shut off, less air is being sucked into the cylinder, leading the air going into the open port to have more charge, as there’s only so much pressure in an N/A manifold for the cylinders to draw from.

Well, you're opinionated but not informed.

Haha okay buddy. I invite you to do the same.
