Got a point there, all just a marketing gimmick, easy enough to make up dyno charts and so called gains, I like the K&N setup just don't like how the filter isn't in a box, when the hoods down its supposed to seal with that gasket but overtime that can get worn and leak
On mine the hood gasket actually works pretty well, but the issue is that the box doesn't even come close to making a good seal on the fender. There's about a 3" gap on either side where it can pull air from the engine compartment at all times. Not the best design, IMHO.
