Charge-air temperature is the hidden power limiter on tuned turbo cars - a Wagner core keeps pulls consistent from first to last.

Wagner casts its own end tanks and CFD-optimizes its cores in Germany, packing dramatically more cooling into factory dimensions - many kits are true no-cut installs.

Wagner Tuning engineers high-performance intercoolers, downpipes, and charge-pipe systems from its facility in Germany, where every product is developed in-house using CAD design and CFD airflow simulation. Best known for its Competition intercooler kits with cast end tanks, Wagner has become the benchmark upgrade for turbocharged European platforms - BMW N54/N55/B58, VW and Audi EA888, Mercedes-AMG - along with turbo Fords and other modern forced-induction applications. German engineering, real dyno gains, direct bolt-on fitment.
