Product Details

The ECS Tuning Luft-Technik Front Mount Intercooler was designed and engineered in-house to provide you with a direct bolt-on system to increase air flow, decrease restrictions, and drastically lower temps!

The R&D team at ECS Tuning has spent countless hours creating and testing a system to optimize performance and efficiency while providing the clean look that Audi owners have come to expect. We designed the intercooler to directly mate with the existing OEM piping, resulting in a simple install.  

ECS Tuning's Luft-Technik Intercooler features an aluminum bar and plate core with cast aluminum end tanks, finished in a silver powder coat with the embossed ECS Tuning logo. The core is not only thicker (3.5" compared to OEM at 3") but it offers a 65.5% increase in frontal area compared to stock intercooler.  Each intercooler is pressure tested to withstand a minimum of 3.5 bar and designed to increase power, improve efficiency, and reduce heat soak. Our engineers provided a proper fit by utilizing factory mounting locations and ensuring that no trimming or cutting would be necessary, making installation completely reversible.

Increasing the surface area by using a larger more efficient core design and providing a smoother air path, we were able to lower temps by 41 degrees while increasing the intercoolers efficiency by 30 percent!  The temperature and efficiency data shows that there is a significant reduction in air temperature leaving the intercooler, which will lead to power gains in high stress and high temperature conditions while reducing the strain on the engine.


Key Features:

  • Reduced intake temperatures and air turbulence
  • Increased air flow capacity
  • Up to 30% improved intercooler efficiency
  • Reduced intake temps by as much as 41*F during dyno runs
  • Pressure drop reduced by 47%
  • Cast aluminum intercooler end tanks
  • Bar and plate design intercooler core
  • Includes all stainless steel t-bolt clamps and hardware 
  • Easy and direct replacement upgraded intercooler

This system is capable of withstanding greater heat and higher boost pressure over factory.  The Luft-Technik Intercooler System was designed with a focus on improving performance while maintaining OEM fitment with the use of quality parts. Attention to detail is never missed here at ECS Tuning, and this is no exception.

  • Cast Aluminum End Tanks
  • Pressure Tested to 3.5 Bar 
  • 23"x11.75"x3.5" Bar & Plate Design Core
