W213 E63 AMG E63s Blow-Off Valve (BOV) / VTA Adapters for Mercedes M177

Fits Mercedes-AMG E63 & E63S • Vent-to-Atmosphere Turbo Sound Upgrade

Commonly searched as an E63 blow-off valve (BOV), these VTA (vent-to-atmosphere) adapters convert the factory electronic diverter valves on the W213 Mercedes-AMG E63 and E63S into an open, atmospheric release system. Designed specifically for the M177 4.0L twin-turbo V8, this upgrade delivers aggressive turbo sound without ECU tuning or check engine lights.

Rather than replacing the entire boost control system, these E63 AMG VTA adapters work with the factory diverter valves to vent boost pressure to atmosphere on throttle lift—producing the sharp blow-off valve hiss and turbo flutter enthusiasts are after.
