BMC's aluminium flexible tubing is 600mm in length and reinforced with cardboard, adding strength and rigidity.

Used for supplying airflow from a cool air source, such as, the front grill/bumper or wheel arch. These are supplied as part of the BMC CDA kits and function as a cold air feed to the 'cold air side' of the CDA. Can also be used to direct cool dense are to a conical filter.

These will not rust and are painted black.
