Description
Enhance the power and responsiveness of your K04-converted 2.0L TFSI EA113 engine with the Neuspeed HI-FLO Turbo Discharge Conversion Kit – K04 for PQ35 chassis. Designed for enthusiasts running a K04 turbocharger upgrade, this high-performance kit eliminates the factory turbo discharge restrictions to deliver smoother airflow, improved turbo spool, and increased horsepower.
At the core of the system is a precision CNC-machined billet aluminum discharge adapter. This adapter features a smoothbore design that reduces turbulence and reversion, resulting in enhanced flow characteristics over the OEM unit. The machined flange lip ensures a tight, leak-free seal to the turbocharger.
The kit includes a high-quality silicone hose that connects the adapter to the final and most crucial component — a modified OEM-based discharge pipe. NEUSPEED modifies the factory pipe by cutting it at its widest section (57mm ID), rolling a lip at the cut point to ensure easy and reliable hose clamping. This allows the full diameter flow path to be maintained, eliminating factory bottlenecks and maximizing the potential of your K04 turbo upgrade.
Best of all, this kit is completely bolt-on — no cutting, welding, or additional modifications required.
