Product Details

10X Entries For Our 25th Anniversary Sweepstakes!

The ECS Tuning Luft-Technik Intake isn't just a performance upgrade—it's a masterpiece under the hood. Our innovative performance design replaces the bulky factory airboxes and panel filters with high-flowing silicone inlets, aluminum heat shields, and dual cone filters, resulting in improved airflow and an intoxicating induction and turbo sound. Let your engine breathe!

Our design starts with dual 4.25” 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. 

FEATURES

  • Dual 4.25” air filters positioned for optimal airflow within the engine bay

  • Silicone inlet adapters are included for seamless compatibility with stock D4 S8 turbo inlets

  • High-flowing open intake design improves throttle response and encourages turbocharger efficiency

  • An aggressive turbo induction sound under acceleration for an exhilarating driving experience

  • Factory-like fitment with no permanent modifications required

  • Silicone Turbo Inlet Adapters for OEM D4 S8 Inlets
  • Aluminum Heat Shields with Pre-Cut Rubber Bulb Seal
