Welcome to FTE!!!

CCV is venting of the oily crankcase gases out to the atmosphere instead of into the turbo & I/C. See here for a better description:
https://www.ford-trucks.com/forums/284862-ccv-mod.html

For the 6637, all you need is the filter (Wix part number is 6637). You may need some 4" OD tubing (like exhaust pipe) to connect the filter to the intake tube, but mine is connected directly. If you do the CCV mod, you'll need some of that anyway, so you might as well use a piece there, as well. You'll need an extra clamp too if you use the pipe.

There is a TON of info here on just about everything you can do to your truck:

What is the reason for removing the foil wraping around your pipes? Isnt it there for a purpose. Does it give you a different sound?

A little more turbo noise.

Two reasons: Looks MUCH cleaner under the hood without that junk on there, and you get a lot more whistle in the higher RPM range. Doesn't change much in the lower ranges, but I definitely notice it in the higher range. Now with the WW, it screams like a banshee when I get on it.
