Eliminate Structural Failure: The Ultimate Billet Intake Upgrade
For high-performance Mercedes-AMG GT builds, the factory plastic intake manifolds represent a significant liability. Under extreme boost pressures, OEM plastic units are prone to heat-induced fatigue, seam separation, and catastrophic failure. The PTG X M178 Intake Manifolds are a purpose-built, ground-up engineering solution designed by Premier Tuning Group to replace these weak points with uncompromised structural integrity and superior airflow dynamics.
Developed and tested in-house by PTG performance specialists, these manifolds deliver the scalability required for elite engine builds. Whether you are targeting street supremacy or track dominance, this system provides the precision and durability expected from the world’s leading AMG performance platform.
Precision Engineering & Performance Optimization
- CNC-Machined Billet Construction: Milled from aircraft-grade billet aluminum for maximum durability and absolute airflow precision.
- Optimized Plenum Geometry: Features advanced internal runner geometry designed for balanced cylinder distribution, ensuring equalized air mass flow across the entire M178 engine block.
- Thermal & Pressure Resilience: Engineered specifically to withstand the high-boost, high-temperature environments typical of the AMG “Hot-V” configuration.
- Seamless OEM Integration: Designed for a perfect fit, maintaining full compatibility with factory sensors, the OEM throttle body, and all standard mounting hardware.
Choose Your Configuration: Port Injection vs. Standard
Tailor your induction system to your specific fueling needs:
- With Port Injection: The definitive choice for high-horsepower or ethanol-blended builds requiring secondary fuel delivery. This configuration includes pre-machined injector bungs, custom fuel rail mounting provisions (with injectors), and a dedicated ECU unit for precise fuel management.
- Without Port Injection: Maintains a clean, lightweight profile for those seeking a structural upgrade while retaining the simplicity of the factory direct-injection system.
