Ok, so, Charge Motion Plates...what exactlyare they? I know they're part of the intake system. What do they do?
I've seen Steeda's part number 555-3125 referred to as "Charge-Motion Plates" and also "ChargeMotion Delete Plates". Which is correct?

My understanding is that the charge motion plates have a throttle valve (just like a carborator) that partially blocks the flow of air through one of the intake valves of each cylinder at low speed (I believe it is below 3500 rpm). This causes one intake to have much higher velocity and gives better cylinder scavaging and mixture distribution at low speed, which leads to better low speed torque and fuel economy.
The down side is that the shaft is still in the intake track at high engine speed, which costs you some power on the top end. Getting rid of the valves leads to better top end power at the cost of worse low end power. Take your pick.

Interesting for all the Honda bashing that goes on in many Mustang forums, Ford has implemented what amounts to basically the same Vtec used in the Honda civic EX and same variable intake found in an acura RSX type S on this new Mustang.
Pretty cool technology.
