This air mass adapter allows mounting of a indivduall intake in vehicles with 2.0L TFSI engine (EA113) where the air mass meter is normally installed in the original engine cover. Thus, the standard air mass meter can continue to be used. The adapter housing is a CNC machined high-precision component for optimum flow and perfect fit. The smooth surface reduces turbulence and creates a uniform air flow. Thanks to the 76mm inner diameter, you still have enough air flow for outputs beyond 400 hp.
