Yeah i doubt its a genuine one for $50

I paid alot more than that for one second hand about 4 months ago.

I am told (by a reliable source) that if going for an aftermarket BOV, the HKS SSQV is one of the better ones to go for because it is a "pull type" BOV thus able to hold boost levels with out leaking like other "cheaper" or "push type" BOV's.
