(I MEANT CRUSHED IN TITLE) as in the title wtf is the difference between the two, it one literally crushed?? lol i owuld post thi in FI but this forum moves faster and i know some of you have DSM BOV on ur cars thanks i advance

 

i guess you're referring to the OEM DSM valves?people put them in a vise and slightly crush the top in to put more pressure on the spring.this helps prevent them from leaking at idle and perform better.honestly,i'd spend a little more money and get a nicer aftermarket BOV.
