Description:

Loud and Distinctive Sound
Possibly the most distinctive dump valve around! The HKS Super Sequential Blow Off Valve (SSQV) is unique in both its sound and operation. The SSQV produces a high pitched WRC style 'chirp' when releasing unwanted pressure helping the turbo continue to spin reducing any lag in between gear changes.

Ability to Handle High Boost Pressures
Machined from billet Aluminium to the highest standards the SSQV can handle standard to very high boost pressures as a result of its unique 'pull type mechanism' whereby the boost actually helps hold the valve shut totally eliminating any boost leakage.

Model Specific Fitting Kit
Model specific fitting kit included in each pack, including vacuum hose, ties, bung, etc.

Dual Valve Structure, Sequential System
At low boost ranges the Primary Valve opens, and at high boost ranges the Secondary Valve also opens, resulting in linear response and optimal blow-off operation at all boost levels.
