The HKS Super SQV Parts - Special Fin Insert Purple is an optional part for your HKS SQV Blow Off. The great thing about the HKS SSQV Blow-Off Valve is that HKS makes a line-up of customizable option parts. This is one of the cooler things for your blow-off, it will change the way it looks and can accent your engine bay with the metallic finish. The sound of the actual blow off will change too, so it is a great way to liven up your turbo system. The Purple Finish Fin has the same shape and sound as the standard fin. It sounds high frequency from low boost to high boost.
