Blow-Off & Diverter Valves
Blow-off valves (BOV) vent excess boost pressure to atmosphere on throttle closure; diverter valves (DV) recirculate it back before the turbo inlet for quieter operation. Both prevent compressor surge and protect the turbocharger. Upgrade factory plastic DVs when running more boost than stock. Note: vented BOVs on MAF-equipped vehicles can cause rich running.
