034-145-5001 - 034Motorsport Diverter (Bypass) Valve, OEM 710N

OEM "710N" bypass valve with reinforced rubber diaphragm for longer use than other plastic valves. This is the best factory plastic valve ever produced.

These are a budget route when looking to replace or upgrade your stock valve, but are still plastic valves that degrade with the extreme temperatures and pressures of the turbo engine. Bosch no longer makes this valve but we offer equal "OEM" grade versions (not a cheap Chinese imitation valve) from Kayser and others, quality and function is identical and unchanged.

For a life long solution, we recommend you consider our all metal 034 Bypass Valve.
