HKS SSQ Blow-Off Valve

hey every one watup im new to this place. i have a question and need sume suggestions. i just bought a HKS SSQ Blow-Off Valve for my evo 9. do you guys think i should installed it or no. i been asking around and i get alot of yes and nos so i tought i just ask an all mitsubishi forum. i bought this at a flea market super cheap less than a 1/4 of the prices. well anyways any suggestions would be good thanks. 

NO!!!! period.  TRUST me.  I used it on my Evo and it was a huge mistake. 

NEVER buy car parts 1/4 of the regular price.  EVER!
 
If you do... NEVER install them on a car you bought for more than 1/4 ACV.
 
C''mon, seriously.  Flea Market / Yard Sale parts have no buisness on a sophisticated machine.
 
Hey everyone, I bought an artificial heart at a yard sale for 1/4 the price of a new one... should I instal this in my grandmother?  I''ve heard a lot on the "artificial heart" forums both yes/no.  I know this "surgeon" who works out of a boarded up factory on the bad side of town who is sure he can put it in there (and get me a good deal on a new manifold for my Lancer too) and the guy I bought the heart from told me it was only used to get to church on weekends so I know it wasn''t abused.
 
Don''t do it.  You bought a paper weight.  Don''t instal it, don''t resell it.
 
Never buy performance parts 1/4 off unless it''s a hell of a sale at a legitamate merchant.  No to eBay... No to flea markets... no to yard sales.  ''Nuff said.

I am betting he bought an HKS ''style'' BOV on eBay. Whoops...knock off.
