    Can the stock air-box on the TQS be modified to improve airflow or is it best left as standard?

    Not interested in cone filters or different panel filters as I am aware that these are not good for our turbos.

    Just want to know if I can help the old girl breathe at bit better.

    Cheers all :thumbsup:

    proven to beat most aftermarket filters on a flow bench test on vortex
