Does anybody still sell dual throttle body intakes?

If you are talking about the 2.8 dual intake, no. That was made by black top racing and didn't sell very well.
The intake was $2,000 by itself and caused the engine to run lean at higher RPM's.
BTR did mention that they will be designing a new one tho, so hopefully it is cheaper and they can give a guide to tuning the ECM to run
it properly.------------------
Every fiero has a story, It's our job to keep that story alive.

I would certainly love one they do look the part just no point unless better than stock.

Anything that breathes as deeply as that intake most certainly does, is going to require the tune to be tweaked. That should be a given.
If it doesn't, it's not worth doing.

If it's true that it can cause the engine to run lean then yes, there are gains to be made as Raydar said.
I started designing parts to make a dual TB setup for the Fiero. I lost interest but would pick it up again if there was enough interest.

Actually we couldn't keep up with the demand, we had a 16 person waiting list who were begging us to put money down on one, but even at $2,000 the production process was crazy and not worth it:
We had to hand-fabricate the plenums, mill down a stock mid-intake and weld on a plenum mounting flange, port the mid-intake, manufacture throttle body adapters, manufacture a vacuum plenum, hand-fabricate the air intake pipes, modify both throttle bodies (remove IAC and TPS from one or the other), modify the PCV fittings, modify the vacuum lines, and manufacture (by hand) a throttle body linkage with throttle plate adjustment. Each one took probably $450 worth of materials and 40-50 hours of skilled fabricator labor.
We only sold 5 or 6 of them, but I wouldn't say they didn't sell well. Also, the intake didn't cause the engine to run lean at high RPM. Something in the tuning caused it to run rich at mid-high RPM. A simple ECU chip tune from Sinister Performance rectified the situation for $100.
The only way for us to build this style of product again is to incorporate some sort of CNC milling or 3D printing to replace some of the long hours custom fabricating different pieces. But even at $900, how many would we sell? Would it even be worth it?

Hey Chris, the pictures you showed look great.
I definitely think there is a market for this. 2.8, 3.1, and 3.4 engine users could easily benefit from this. The look of them is very eye catching, and would stand out from the crowd. People like to do the DAWG modified plenum, and plenty of others for their cars. But this would be the #1 choice for users. I think you'd see a good increase in sales if the price was dropped a bit. Even $1,000 would be reasonable enough for the average Fiero owner to buy.
