Unleash Maximum Performance
Ready to take your BMW F90 M5 or F91-93 M8 to the next level? Skip the core charges, long lead times, and restrictive factory housings—VTT has you covered with our 100% newly cast "GC" and "GC+" turbocharger upgrades.
We preserve what BMW did correctly, while eliminating every OEM limitation: small inlet restriction, inefficient bearing housing oiling, undersized thrust structure, and anything else holding the platform back. Then we incorporate proprietary VTT enhancements and cast all components to OE quality standards.
The result is a true drop-in turbocharger solution capable of delivering 900–1000WHP with the GC, and 1200+ WHP with the GC+, while maintaining near factory spool and full compatibility with OEM oil, water, downpipe, and charge pipe connections.
WE HIGHLY RECOMMEND ADDING the BOV KIT! This will increase turbo longevity!

VTT G90/G99 M5 Complete Turbo-Side Intake System
VTT is proud to announce the first and only intake system for the G90/G99 M5 that eliminates every factory restriction from turbo to filter. Other “intake kits” on the market only replace the upper half of the system — leaving the restrictive factory turbo inlet piping in place. That is the actual primary airflow choke point… meaning those kits only solve half the problem.
Our system removes the entire factory tract and replaces it with precision-engineered billet 6061-T6 adapters that bolt directly to the turbochargers, transitioning into reinforced 2.5” → 4” high-temp silicone and finishing with dual VTT 4” dry element filters.
This is a true full-flow system — no factory bottlenecks — the S68 finally breathes correctly.
