Anders Jacobsen, Tom Hilde, Anders Bardal and Andreas Stjernen jumped their way to 1577.1 points - 47.8 more than their Austrian rivals who claimed second place.
With eight rounds still to go the overall title is still very much up for grabs, and this result sees the Norwegians move to within 257 points of the summit.
Olympic bronze medallist Jacobsen's combined effort of 418 points was the highest individual score of the day in Germany with Austria's Stefan Kraft managing 213.5.
Slovenia edged out Germany's home jumpers into third, but their hopes of gate-crashing the top three in the overall standings appear forlorn with a 538-point gap to make up.
