I started to work with the "scoop" part of the intake.

Some cardboard and the plastic trim

After abit of work, I use some paper to get the basic shape I wanted, so I can Bondo it later for a more better curve.

Used some chopsticks to help guide me on how high the scoop should be.

Now with cardboard cutout and one less piece of chopsticks.
May need to fill the hole...so the during vacuum it stay petty much the "finsh" shape
-NOTE, I'll be using an 1/8 inch thick plywood instead of cardboard.
P.S. basic concept design for the build
I'm thinking for the airbox itself, I'm going to make it out of carbon fiber, the nuts and bolts may have a bushed aluminum look or it can be powder coated with black, and everything else out will be flat-black painted fiber glass.
Edit:

Started to work from paper to cardboard and then to plywood

MARKED!!!

Working on the base of the airbox itself...

The black dots are for the peg, so I can reuse the battery tray

Done....for now
