it Seems logical, but i can never understand why things like this simply aren't marketed with 3 or 4 different engines, or vehicles, strapped to a dyno with "amazing" results. a 4 min video, and it either rides or dies.

We tested a 427 CID engine the other day in a cell, and were able to KILL 50 HP with a certain type of air filter assembly. We have a customer in the field with the same air cleaner saying it "feels better" "feelings" aren't always what they seem!

Simple. That's because stuff like this is snake oil. Always easy to spot because there's never empirical data to back anything up. Comparing before and after videos of someone revving the engine is subjective, as anyone could rev the engine slower or faster to easily show a difference. To me, the bottom line is this. If these things were"tits" they'd be on every single production Holley style carburetor built. They're not. So for me, nuff said.
