THIS IS JUST AN INSERT. THE SSQV4 BOV IS SOLD SEPARATELY.
The HKS SSQV4 blow off valve produces one of the most distinctive BOV discharge sounds and looks great while doing it. These HKS SSQV4 inserts however, allow you to fine tune the sound and look of your HKS SSQV4 BOV to perfectly suit your individual tastes. The Gold insert uses a traditional 3 fin divider and produces the same type of high frequency sound as the standard insert but has the added benefit of a brilliant gold appearance. The Purple insert uses a round type divider that produces a lower frequency noise and looks great as well! Both inserts can easily be installed in a matter of minutes without complicated tools.
