Overall I found a 2-3g/s improvement in airflow with a stock box more gains should be made with an induction kit.

I chose to make a slight revision in that complete removal seems to be a concern as there is a mesh designed to protect against large objects heading towards the turbo.

I decided to remove all screens but modify the front so that its structure and collar were retained.

This could be refitted to allow the metal screen to be retained.

All the grills need to be removed along with the maf unit, then refit the front grill and use the assembly to help modify the grill.
