Does anyone recognize this intercooler?

Curious if anyone might have any idea on this intercooler setup? It’s from a car in japan likely from around 1985/6. The cars build is fairly well documented around the time, but the intercooler remains an anomaly. Please see the following post for an image. I goofed in uploading into this post.

Thanks in advance!

If you zoom in it says Leistung on it. That's German for power. There is a German shop by that name.
