Why oh Why

After numerous people saying it and numerous threads on the subject are people still wanting to add a/m intakes on trucks that at most have a "chip" on them? Despite huge amounts of evidence on stock intakes flowing more then enough and within the truck's powerband, people still want to think an a/m intake is the best thing. Are a/m intake ads that good or is what Barnum said really true?

I think alot of folks (I thought this way at first too) are coming from gassers that NEED intake kits to get more air in and exhaust to get more air out thus increasing HP... The a/m suppliers continue to drill this into diesels as well...

well at 70 bux a pop for a filter or 269 for a s&b with a washable filter which is way easer to change, and can filter dang close to stock. thats why i think ill be getting an s&b filter.imo

I still don't understand how a filter with less filtering material can flow more air and filter just as good as a stock 6.0 filter.

The biggest thing is that a/m filters do flow more then stock, but they don't flow more then stock til you hit 3,700 rpms. Look at the valve cover, 2,000 rpm for peak tq and 3,300 rpm for peak hp. That extra flowing air doesn't come til well after the powerband of the 6.0. That's using charts of some of the top brand filters, but they focus on the fact that it does flow more, which it does, but it doesn't flow more til it's too late. I don't really most people know what rpm that peak tq/hp comes at, they just know peak hp for sure and may tq depending on what they are using the truck for.
