I've only seen them on JDM sites and can't find any info on them. Like how they sound, or work.

 

Well, it's a blowoff valve, are you asking how a blow off valve works? If you're asking about being two, its because it's on two different pipes on the 300ZX.

Theres a HKS SSQV video, its near the middle. Sound good to me.

 

Nah I know what it is. I'm just saying I've never seen that style of HKS b4. I just want to know it really is HKS and if it's a dual stage pull-type BOV like the regular SSQV I always see.

 

IIRC I've seen that BOV on a freshly imported SR20DET before

 

i believe that is the first gen sequential type bov from HKS....can anyone confirm this?

 

that *sounds* right but i cant say for 100% sure

 

I'm almost postive it is

 

The seller finally wrote me back he says that's what they are.
