BYPASS VALVES (BLOW OFF VALVE) 944T
Aluminum BOV "Bypass Valves"
Direct replacements for the original stock plastic Bosch Bypass Valve. We have 2 different models to choose from.
These aluminum BOV's are direct replacements for the plastic OEM type unit. A ruptured BOV can cost you 45 or more RWHP and cause the boost to come on very lazy. A blown BOV during a competitive event can mean moving from first place to last place.
