CTS Turbo BMW N20 BOV Blow Off Valve Kit

Upgrade your BMW N20 turbo engine with the CTS Turbo Atmospheric BOV Kit. This BMW N20 blow off valve kit replaces the fragile factory plastic diverter valve with a compact, fully serviceable T6061 billet aluminium unit that delivers great turbo sound, improved reliability and seamless integration with OE electronics. Ideal for those searching for a BMW N20 dump valve, BOV, or diverter valve upgrade, this CTS Turbo blow off valve kit is a proven performance and durability enhancement for N20-powered cars.

Why choose the CTS Turbo N20 Atmospheric BOV Kit

  • T6061 billet aluminium construction for strength and durability
  • Black anodised stealth finish
  • Fully compatible with OE electronics and will not trigger a check engine light
  • Fully serviceable piston design for long life and easy maintenance
  • Significant reliability improvement over the factory plastic diverter valve
  • Compact design fits easily in the tight N20 engine bay and is slightly shorter than the stock unit
  • Replaces the OE unit that is prone to torn diaphragms, cracked plastic and electrical malfunctions
  • OE recirculation valve wiring harness requires modification to connect to the solenoid
  • Great atmospheric blow-off sound and excellent value

The CTS Turbo N20 BOV kit is designed to work with all factory electronics without causing any dash warnings. It maintains proper ECU communication while giving that desirable atmospheric blow-off noise many BMW N20 owners seek from a dump valve or BOV upgrade.

Fitting and installation

No need to remove the factory turbocharger. Typical installation time is 60 to 120 minutes, depending on experience. The kit works with OEM electronics, and the OE recirculation valve wiring harness requires modification to connect to the solenoid as part of the install.
