I can see merit for the Ram Air model (top one) but unless there is a pipe from the front of the car to it how it can be an "Air Ram". It would simply suck the air from where the resonator was. Removing the fog light would help a bit.

I cannot see how the Super Cleaner (bottom one) would get much cold air unless you removed the fog light so cold air is forced up into the engine bay through the existing hole. Maybe if there was a larger diameter pipe from the end of the filter down through the hole to ensure only cold air is sucked then I would be the best of both worlds.

I would probably go with the top one myself but at almost double the price of the bottom one I would rather go with one of the normal CAI's and put up with the low end loss.

As for the bottom end loss, isn't that a result of sucking the air through a longer pipe? Wouldn't a larger diameter pipe resolve this problem?
