Description
Elevate the performance of your 2.0L TFSI EA113 engine with the Neuspeed HI-FLO K04 Turbo Discharge Conversion Kit, specifically engineered for K04 turbocharged applications in Audi and Volkswagen PQ35 chassis vehicles. Whether you’re running a factory K04 setup or a K04 conversion, this direct bolt-on solution removes the bottlenecks in the turbo discharge system—delivering smoother airflow, faster spool, and increased horsepower.
The heart of this kit is the CNC-machined billet aluminum turbo discharge adapter, designed with a smoothbore interior that significantly reduces restriction and turbulence compared to the OEM part. The adapter includes a precision-machined flange lip for a leak-proof seal and connects directly to the included 4-ply silicone hose.
The flow path continues through a 57mm inside diameter mandrel-bent aluminum discharge pipe, which is equipped with a rolled lip on one end to ensure a secure hose connection and a billet aluminum fitting on the other end to interface with the factory intercooler hose. The full-diameter construction removes the OE step-down restriction found in stock pipes, maximizing efficiency and airflow to the intercooler.
With no vehicle modification required, this is a clean and effective upgrade designed for enthusiasts seeking serious gains in response and performance—especially those running performance software or K04 conversions.
