The BLITZ Super Sound Blow Off Valve VD (Venturi Drive) features an all new designed, ribbed, aluminum die-cast body that dissipates heat more effectively and a venturi shaped funnel that creates a sharp dynamic sound that adds to the driving excitement and feel. Employs the advantages of the "Dual Drive" mechanism from the previous Super Sound Blow Off Valve for maximum turbo response, relieving compressor surge without reducing compressor speed. A special lubricated coating ensures smooth movement of the piston even under dusty conditions while a large diameter valve and unique rubber seal provide outstanding sealing ability at high boost. 100% genuine BLITZ product.
