Yes it’s been put in many production cars. My 92 Mazda MX3 has variable intake manifolds.
Tvis in the 4age
My Civic 2014 1,8L also has variable intake.
WHEN T-VIS KICKS IN!!
This has been done to Mazda CX 9 with turbo Skyactiv . They use variable exhaust manifold to keep turbo always spinning to eliminate lag. Check out savagegeese on YouTube. His last video shows the actual setup.
Variable exhaust and variable intake are two different things, even if they work on same principle.
So the BMW DISA System as seen on the m54b30 is one of those Systems? Does it also use the bouncing pressure wave or only benefits from having variable length / diameter?
Here is how mazda solved it with the r26b engine for the 787b. The best part about this is that they can change the lenght at any rpm, and isnt just two different barrels, with different lenght, with a valve that change barrel.

Can it be used with a turbocharged engine, to give a bit more “POWAAAAR” to it?
EDIT: Found a list of all the cars that use the technology https://en.wikipedia.org/wiki/Variable-length_intake_manifold
