Do all the cheap BOV's make a "pssshhhht" sound or are they the recycling kind
cheers

 

when i say cheap i mean the ones you can find on cars as sotck or the bosch kind... thanks

 

The stock dsm bov's are actually pretty loud, reason is most factory cars vent the blow off valves back into the intake pipe on the inlet of the compressor. Most guys with hondas just vent them to atmosphere. so they are pretty loud. The bosch bov is pretty quite.
