Swapped out the stock under-dash vents for the Ächtung Kraft units. A big thumbs up for these. Had the targa top off this morning at 45º and the heat was blasting my passenger and I right at our lower torso's keeping us toasty warm.
Guessing the fresh-air blast in warm temps will be equally appreciated.
Definitely worth the price of admission.
FYI: To make these fit on my '71 Targa I had to grind away about 1/16" from the back edge. Once I did that the fit was perfect.
Stock vent on the left, Ächtung Kraft on the right. Directs the air right at you!
