Here's my attempt at making a warm(er) air intake for my car. I had previously cut away a section closer to the front of the car. The current cutaway is behind the top radiator hose, closer to the engine. The old cut is closed off to ensure the intake air is coming from the engine bay. I also have a grille block, so I'm hoping the combination traps enough warm air.
Here are some photos:

Have not had a chance to test it yet. Feedback welcomed!
