How many runners do you see with them? Answer: few to none because they’re already breathing through something significantly larger called a mouth. The sports where increasing your nasal passage size helps is when your mouth is obstructed by something like a guard. Nice try but not really relevant.
Those intakes look so much like the original ones that I think they’re not worth the extra money, especially if the vehicle gets driven in town half the time. If I drove between Bangor and Houlton Me. all the time, I might want one. Speed limit 75. We all know I have never driven that fast with the 69 428 Cobra Jet Torino, the LTD with the 390 or the Firebird. Good thing I never got a ticket for going sideways down a straight road at high speed either. Some things just aren’t done. Cars can go fast without hepafilters.
