HKS Purple SSQV Insert (round)

This HKS Purple SSQV Insert is a round-style replacement diaphragm for your HKS Super Sequential Blow-Off Valve (SSQV). It's designed to help your blow-off valve function correctly by sealing tightly when the valve is closed. A good seal is important for maintaining boost pressure before it needs to be released.

The purple color indicates a specific spring tension, which is tuned for certain boost levels. If your existing insert is damaged or you're looking to ensure your SSQV is operating at its best, this direct replacement is a solid option. It's made to fit HKS SSQV units, so you know it'll work with your existing setup.
