Fly, you are absolutely
CORRECT! The 2004 anniversary 550 and the 987's utilize the same basic design concept as the EVO intake. The airbox is built as an all encompassing unit, not like the EVO that utilizes panels to seal the air filter from the engine compartment.
Below; 550/987 airbox assembly breakdown ($560+ tubing from airbox)

The filter is an oval, tube shape like the EVO, but
a lot bigger to allow more unrestricted air flow. It's design is a straight shot from the left hand intake port, through a big snorkel (to probably suppress sound), to the filter and to the MAF. The 550/987 intake set-up is an OEM answer to the EVO intake. Porsche engineering at an EVO price, and you can to install it on your car.
