BLITZ VD Polished Turbo Dump Valve Kit (Model 70183) for Subaru Impreza GC8 & GD Series

Description

Blitz Venturi Drive Super Sound Blow Off Valve – Release Type
The all new ribbed main body dissipates heat more effectively and the venturi shaped funnel creates a sharp dynamic sound.
Venturi Drive dump valves also feature “Dual Drive” for maximum response, a small port for low boost and a larger port for high boost.

Manufactured from die cast polished aluminium with a brass piston and a rubber diaphragm, meaning they can easily cope with boost pressures up to 1.2 bar with the supplied spring.
There is an alternative hard spring for boost pressures above 1.2bar and also a soft spring available for very low boost applications. (please see DV Spares)
They are also tension adjustable.

This kit is a Release Type and includes everything needed to install onto your vehicle.
