Product Description

For those looking to maximize performance, a compressor bypass valve (CBV) upgrade is essential to sustain peak boost levels and extend reliability of your turbocharger. All Volvo turbochargers are fitted with a stock CBV which utilizes a rubber diaphragm and spring to recirculate boost back into the intake system. Because the stock CBV is designed for stock boost levels, its lifespan is significantly shortened once you increase boost (tuned engine software, etc.)

S40/V50 and C30/C70 CBV Upgrade Features

The S40/V50 and C30/C70 CBV Upgrade Kit for the KKK K04 turbocharger features a piston/spring operated valve for maximum reliability. Whereas a rubber diaphragm can get brittle and potentially crack from overuse/aging, a piston style valve is much more durable. The CBV also has an enlarged recirculation valve to accommodate the increased boost/air flow from tuned engines, minimizing boost spiking, etc. The S40/V50 and C30/C70 CBV Upgrade is fitted with a spring suited for up to 1bar boost and features a angled vacuum port for additional coolant pipe clearance.

Vehicle Fitment:

  • 2004.5 - 2010 S40, V50 T5 (FWD/AWD)
  • 2006 - 2010 C70 II T5
  • 2007 - 2013 C30 T5

 

While you're at it...

If you plan on replacing your CBV with one of our upgrade kits, we also highly recommend replacing the original rubber vacuum lines with more durable silicone lines. The rubber vacuum lines can harden and get brittle due to excessive heat and aging, which will ultimately lead to a boost leak! We offer replacement 4mm ID Silicone Vacuum Lines in either blue, black or red colors! Click here for more info...
