I just ordered these with BMC filters for my M5...can't wait to see if I feel a difference! 
I'll be removing my charcoal filters at the same time.
I'll report back next week.

RPI ram air scoops and AFE CAI don't mix. It's one or the other.

Seems like the two would complement each other. The ram air scoop would allow you to feed the motor a denser charge of air, thus increasing power (with the right amount of fuel added to compensate of course). It seems logical to me, then that you would want to be a little methodical with this scenario. First, add a cold air intake (AFE, DINAN, ETC.). Then, add the ram air scoop. After that, get the ecu remapped. That should do the trick, being that the remapped ecu will be able to see the extra air flow and be able to correspondingly adjust air/fuel ratios, ignition timing, and the like to take advantage of it. I have never seen a picture of the AFE cold air intake before, but if the diameter of the piping was decreased by say, 3mm, while adding the ram air scoop the effect should be that velocity would be increased while at the same time increasing volume. Good response, more power, better fuel economy.

i have both. i was thinking the same as pentiumpush since seeing that the end of the outlet is in the area where the filter of the AFE is

You have both? So does this mean that the RPI scoop is available to non-M owners?

He worked with Eloy to make the prototype for the 530, so he has the only one on a non-m5 E60

I spoke with Eloy of RPI and he says that AFE CAI will not work with the scoops. As for NeRwEEzy having the only non-M5 scoops, there's a reason. RPI will only produce performance parts that show a measurable gain on the Dyno Dynamics. NeRwEEzy's 530i was dynoed pre-scoops and with the scoops. There were no gains to be had. The 535i/545i/550i might show gains.

Spoke to Eloy at RPI and he said that he can make a ram air scoop for the 545s if there are atleast 20 people interested in it, Dyno it and design as required for the 545
or
If the number is lesser he can do a production run of just the one side of the scoop they make for the m5 and sell it to us for $100 although he cannot gaurantee the hp gains in this case.
Is the intake tube behind the front grille different on the M5 compared to the 545? (if we consider the right side alone)
Shouldn't the amount of air coming into the intake tube be the same for both cars if the design of the grille and the scoop is the same ?
The way the engines breathe and utilize the air coming in might be different hence different hp gains but the purpose of the scoop should have been achieved.
Am i correct in making this assumption ?
