Description
HKS SUPER SQV4 RZ34 VR30DDTT (hks71008-KN030)
**available for pre-order**
The HKS SUPER SQV (Sequential Blow-Off Valve) employs a unique two-stage sequential valve structure
using primary and secondary valves. It features a differential pressure control system that delicately
manages pressure across a wide operating range from low to high boost. Unlike typical blow-off valves, its
"relief-less operation system" suppresses relief at high boost, maximizing charge response during repeated
boost and release cycles with throttle ON/OFF.
【Features]
Blow-off valves are placed on both banks of the VR30DDTT engine, quickly releasing
unnecessary boost pressure from each turbocharger, reducing their load (when the throttle
is off).
Hoses between the turbocharger and intercooler are replaced with dedicated 4-ply silicone
hoses for the SQV4, strengthening the hose section.
All parts except the SQV4 main body are in black to highlight the SQV4.
The return hose uses a dedicated molded silicone hose, fitting snugly in the engine bay.
