Product description: Our milled chamber intake manifold for the 2.5 TFSI replaces the standard gap intake manifold. Gap intake manifolds are very efficient up to a certain power or boost pressure, as all cylinders are filled evenly. If boost pressures of 2 bar or more are used, we achieve significant increases in performance with our gap intake manifolds. Even with a level 3 with TC870XT, or TC900XT and similar turbochargers that produce over 2 bar, at 660hp there is already an increase of 30hp just by replacing the intake manifold.  Stage 4 cars with a reinforced engine and a proportion of alcohol in the fuel, the intake manifold already achieves increases in the range of up to 50 hp. Not only does the peak power increase, the entire filling across the entire speed range is improved, which means the torque increases constantly. Please also note our performance diagrams in the product description. Please note:In accordance with our general terms and conditions, we would like to expressly point out again here that all items that are not expressly marked with a TÜV / EC approval do not have approval in the area of ​​the StVO.
