VTT BMW S68 Upgraded DV Kit
For G90, G99, XM, and all S68-powered models
Looking to wake up your S68-powered BMW — G90 M5, G99 M5 Touring, XM, or other variant — while improving boost control and ditching those restrictive plastic factory diverter valves?
We’re proud to introduce the VTT Upgraded DV Kit for the BMW S68 — designed for enthusiasts who want better performance, quicker boost recovery, and the option for that addictive BOV soundtrack.
Our kit replaces one or both factory DVs with high-quality billet Turbosmart units, available in:
-
Plumb Back (OEM-style recirculation — no added noise)
-
Dual Port (atmospheric vent — signature BOV sound)
Choose the setup that fits your goals and installation comfort:
1. Dual Plumb Back DV Replacement — Stealth Performance
-
Sound: No extra noise — maintains full OEM quietness.
-
Benefit: Smoother boost control, better sealing, and higher durability.
-
Install Difficulty: High — driver-side DV access requires removing the driver intake, and in some cases the driver intercooler or charge pipe.
-
Best For: Drivers wanting reliability and performance without any change in sound profile.
2. Single Passenger-Side Dual Port DV Replacement — Quick & Loud
-
Sound: Crisp BOV release on throttle lifts and boost dumps.
-
Benefit: The easiest way to add audible excitement with minimal install time.
-
Install Difficulty: Low — 5-minute swap, no need to remove intakes or intercoolers.
-
Best For: Those who want sound and performance without the hassle of a full install.
3. Dual Dual Port DV Replacement — Maximum Vent & Attitude
-
Sound: Aggressive, unmistakable BOV sound on every lift.
-
Benefit: The ultimate vent-to-atmosphere setup for sound and response.
-
Install Difficulty: High — same as dual plumb back installation for driver-side access.
-
Best For: Enthusiasts who want the loudest possible vent sound with full performance benefits.
Kit Includes:
-
One or two Turbosmart billet diverter valves (your choice: plumb back or dual port)
-
Direct-fit hardware for the S68 platform
Technical Highlights:
-
CNC-machined billet aluminum housings for precision fitment and maximum durability.
-
High-temp Viton sealing for reliable boost holding at extreme temps and pressures.
-
Faster response time than factory units, reducing turbo lag between shifts.
-
Designed to handle significantly higher boost pressures than OEM plastic DVs.
