Description

Take your AMG V8 twin-turbo (C63, E63, GLC63, GT, GLE63, GLS63) to the next level with the ZAC Motorsport V8 RPA Mechanical BOV Conversion. The stock electronic diverter valves bleed boost and fail under high pressure, robbing your engine of performance and muffling the soundtrack. Our RPA system replaces them with twin fully mechanical valves for uncompromised boost control, sharper throttle response, and the addictive turbo blow-off sound.

  • Boost that holds: Designed for Stage 2+ power levels, this setup keeps the turbos efficient and responsive..

  • Twin valve upgrade: Keeping it Australian! Two Genuine Turbosmart VeePortPro valves ensure flawless reliability under load.

  • Error-free performance: ECU simulators include, no check engine lights or limp mode.

  • Motorsport-grade construction: CNC-machined 6061 billet aluminum with an anodized finish for strength and style.

  • Fast install: Complete bolt-on package with supplied T-fittings, typically fitted in 15 minutes.

  • Aggressive sound: Crisp turbo flutter and sharp vent-to-air release that amplify the raw V8 soundtrack.

This is the go-to upgrade for M177 and M178 AMG platforms where serious boost, reliability, and sound matter. Experience what your AMG should have felt like from factory.
