the term explains itself la...
blow-off...blow..off~ duh.....
sqv means sequential blow off by hks...plenty of aftermarket blow offs.
some stock turbo cars are 'blow-in',so it recycles the air...*correct?*
PocRoc.. blow in.. i like your term.. its still a blow off valves.... just that we recycle so we don't face some problems.. and not noisy.. for cars with MAF sensor better to recirculate the air.. hehehe
