ECS D4 4.0T Performance Intake System & Turbo Inlets

Our design starts with dual 4.25 inch air filters strategically positioned on both sides of the engine bay to make use of all available space. By increasing the volume of incoming air, this design ensures a steady, unrestricted flow to the twin-turbocharged 4.0T engine. This results in faster spool times, improved throttle response, and increased overall efficiency. The filters are fed by large, high-flowing inlets, precision crafted for an exact fit with factory turbocharger inlets. These inlets are manufactured from high-quality silicone, increasing component durability and eliminating the factory corrugated design in favor of increased airflow.

To reduce intake air temperatures (IATs), our system features aluminum heat shields on both sides of the engine bay. The Luft-Technik kit includes pre-cut rubber edge trim, sealing the airboxes to the underside of the hood to prevent hot engine bay air from entering the airbox. Twin billet aluminum adapters seamlessly adapt the silicone inlets to the heat shields, providing a reliable seal that eliminates the possibility of air leaks in the intact tract.
