E63 & CLS63 AMG M157 Charge Pipes | Turbo Pressure Relief Kit

Protect your turbochargers and upgrade your forced-induction system with the Turbo Pressure Relief Kit, engineered specifically for Mercedes-AMG M157 V8 Biturbo engines. This precision-designed kit helps prevent compressor surge, reducing stress on turbochargers and supporting long-term reliability—especially on tuned or aggressively driven AMG applications.

Unlike factory recirculation systems that can allow pressure backflow during throttle lift, this system safely releases excess charge air, helping protect turbo internals and maintain consistent boost behavior during hard acceleration, rapid shifts, and spirited driving.

Key Features & Engineering Highlights

• Side-Mount Design: All current kits feature a side-mounted pressure relief valve configuration for improved packaging and consistent operation (not center-mounted).
• Enhanced Turbo Protection: Relieves excess boost pressure to reduce compressor surge and minimize turbocharger stress under high-load conditions.
• M157-Specific Design: Optimized for the airflow demands and boost characteristics of the M157 twin-turbo AMG platform.

Complete Kit Includes

• Modified charge pipes
• Custom silicone 90° elbow
• 38mm pressure relief (blow-off) valve
• MAP sensor tap
• Vacuum lines and required installation hardware

Factory Integration

This kit is designed to retain the factory AMG engine cover. Minor modification to the engine cover mounting bracket is required to ensure proper clearance and fitment.

Installation Notes

• Approximate 2-week preparation time prior to shipping
• Cutting of the engine cover mounting bracket is required
• Professional installation is recommended for optimal results
