Well I just noticed that Dinan finally came up with a CAI for the 550 guys. Their price seems a bit expensive though... Any thoughts or opinions?

"High Flow Intake System
Dinan's high flow intake system for the 550 dramatically increases intake air-flow volume and velocity as well as ensuring the lowest possible intake air temperatures for maximum power gains, as well as improved throttle response. The system takes full advantage of the ram-air effect by adding a second air inlet in conjunction with the stock configuration, force feeding more cool, oxygen rich air to the enhanced air box. The system includes a complete replacement air box and lid, designed to increase overall volume and accommodate the additional air inlet. A special high flow filter element is included, reducing the restriction presented by the stock filter. The air box and lid are molded from a composite material that has been chosen specifically for its ability to resist power robbing under-hood heat and the design provides for a completely sealed air box, maximizing pressurization for optimum performance. Air from the secondary inlet passes through custom molded ducting, including a visible section manufactured from carbon fiber, also designed to reject underhood heat and provide maximum flow.
The high flow intake system alone produces a substantial 18 horsepower gain. The intake note takes on a subtly more aggressive tone at wide open throttle that will be music to the driving enthusiasts' ears."

$1200 is a little on the steep side I think. Then again, it has some pretty decent gains and it's Dinan. To me, $500-800 would be more fair (eventhough that's still very $$$ for an intake)

Your pretty much paying for the brand name, i dont see any difference spending $50 on a kn filter adding some rpi scoops vs this dinan intake, pretty much the same hp gains for fraction of the price.

that's a lot of money for an intake but 18hp is a bid diff. +1 on the scoops!

Info on the fan Dinan uses to get the gains quoted: Dinan uses a 38,000 CFM fan used in the ventilation systems for highrise buildings. Impressive, impressive unit. Gains would of course be different if you dyno using the typical 2k to 15k cfm fans most dyno shops use.

interesting. what would the reported gains be if the fan was not turned on? Just curious, I am considering this mod, and the response to my question will not affect my decision. that's a big fan and I am thinking the stock system would probably show an increase in HP if it was in the blast of that fan!
