text: how can u put a blow off valves?   very simple installation first do some research this is a common upgrade theses days compared to 3 years ago alot of company's make kits that are vehicle specific ... by a kit i mean you will get your tube with a flange already welded to it ...a bov, possibly two hard springs , vacuum hose,snap ring , hose clamps and t fitting .. install your hard pipe or silicone sleeves into place find the best place for the bov to to sit good clearance is something to keep in mind .. place your bov in the flange use close snap ring pliers to secure the bov to the flange now splice a main vacuum to the manifold your tee t fitting will go here run the vacuum hose from the bov to this t use hose clamps on both ends of the vacuum ... dont worry about tuning this since you bought it vehicle specific  ... installation instructions are also included
