Racing Bypass Valve Type H34 vents excess pressure back
into the car’s air intake making the valve ideal for Mass Air Flow (MAF) metered
cars where venting to atmosphere can create a "rich" air/fuel ratio right after
the valve goes off. The Racing Bypass Valve Type H is CNC machined out of billet
aluminum and brass. Valve operation, while louder than most stock valves, is
quiet compared to a BOV that is vented to atmosphere like the TurboXS BOV-H or
BOV-H-RFL.
The RBV-H34 comes standard with a 34mm OD anodised aluminum
hose adapter for the inlet.
