Product Info
The ProPort combines a billet-aluminium body and valve with a boost-balanced diaphragm design. Turbosmart specifies 420 cfm flow. Its rotatable cap and two 1/8 NPT reference ports help accommodate different engine-bay layouts. This is a universal installation requiring suitable mounting, plumbing and spring selection—not a vehicle-specific bolt-on kit. Confirm engine-management compatibility before using atmospheric discharge.
