If one wanted to install the CAI, K&N filter and tube, I guess you just remove the old factory stuff, including the box?
Then the filter just sits open in the engine compartment. Isn't that hotter than the Snorkel inlet?

It looks cool, but the factory tube and filter look just like the K&N design, only it sits in the box, which is covered and gets its air source from the snorkel.
I'm confused! Does it really change anything?
