Any A/M intake that eliminates the stock "Choke Points" is going to give your SRT much needed performance gains.

The stock engines can only move so much air - after that you need to move on to pulleys and exhaust modifications etc...

It all boils down to time tested consumer marketing points; price, appeal and brand loyalty.

Those seem to be the major points I see discussed on this forum.

I haven't seen proof that any single A/M intake will out perform the other.
