Application Scenarios

Engineered for high-performance durability, the S488 turbocharger integrates with S400SX4/S400 twin-scroll systems to enhance power delivery in heavy-duty and high-output applications. Its twin-scroll design improves exhaust pulse separation, maximizing energy utilization and enabling rapid throttle response even under heavy loads. This makes it ideal for long-haul trucks requiring high torque at low RPM, construction equipment operating in rugged environments, and marine vessels with demanding power needs. With its single OEM equivalent (171702), this turbocharger simplifies parts sourcing for mechanics, reducing downtime through quick installation and US-based inventory availability. Each unit undergoes rigorous dynamic balance testing to ensure smooth operation and minimal vibration, supporting extended engine lifespan in high-performance T4-powered vehicles.
