Repairkit Compressor Bypass Valve

While many Volvo turbo models suffer from torn or leaky compressor bypass valve diaphragms not all of them require our heavy duty kit to repair it. This standard kit replaces your stock compressor bypass valve internals with fresh pieces to ensure proper operation. These are the same parts used in our HD kit, but without the higher pressure springs used in higher than stock boost applications.

Symptoms of torn or failing factory CBV's are:

• Delayed boost developement or low boost across the board
• Fluttering or surging when closing the throttle when in boost
• Erratic boost developement
