yes that is the full closed system fitted with the kits, box keeps the heatsoak down and dirt and also has a re-circ back into the K&N, comes with huge cold air feed.
Single K&N with seperate cold air feed will be more than good enough to keep cost down.

I have a k&n and I love it but I have been informed by a few guys who are mountuned up that yes it's expensive but the CAIS is worth it if that's the route you wanna go down
