Are the RPI ram air scoops worth it? Looking at their website right now, and assuming using the M3/M4 models. Still running stock airbox at this point, but looking at the BMC air filter and removing the charcoal filter you mentioned doing as well.

On our S55 M2C's the airbox intakes that exit the filter boxes do not attach to the open radiator sides LIKE THEY DO IN THE F80/82'S.. I had to cut the holes and then I wrapped my intake pipping with duct tape to enclose it.
The intake ducts are open and pulling hot air from the engine compartment so modifying it this way certainly won't hurt
This thread should explain everything:
