Steeda, KN FIPK, JLT, AR..... they all yield relative results.... Make your decision on price and looks.... long as the filter is 9" or larger and it has a heat sheild it doesnt matter much.
The motoblue intake from rpm outlet looks fairly similar to the steeda intake but has a velocity donut. Does the steeda intake have a velocity donut and if does, what does the velocity donut do for performance?
I dont think the Steeda does, all it does is give more surface area, but when you go to the track and pull out the headlight itll allow you to pull in the outside air easier sorta acting like a ram air
actually the "doughnut" as everyone likes to call it is probably on every cold air kit. My example is this I just reacently purchased 2 cold air kits one bieing steeda and the other being mac straight. On the ss you have to bolt the doughnut up to the plate and then the filter clamps on to it. Onthe steeda the doughnut is made as part of the filter. hope I explained that well?
