cobb offers a larger filter to fit in the extra space the speed6 has. and its common sense that more surface area and a greater cone vortex not only compresses MORE air but it gets slightly cooler because it has a longer distance to build speed and vaccuum pressure by the time it enters the intake tube. i think you did mean to sound negative. and offering a better price is called undercutting the competition, sorry guy. of course a bigger filter is better. TOO big isn't, but unfortunately the speed3 guys have to sacrifice filter size because of compact space. im pretty sure speed6 cobb filter is standard size for most aftermarket intakes, and not larger than its supposed to be.
