Product description:
The Stage 4 kit is the most powerful complete package for the RS3 8Y – with consistently selected components for lasting performance at the highest level.
The core component is the TC Turbos X8 upgrade turbocharger , which unleashes its full potential at this stage. It is supported by extensive fresh air optimization and the HP Sport Series intercooler with air ducts , which ensures stable charge air temperatures even under high thermal loads.
The exhaust side is realized via the powerful HP 4" downpipe with underfloor catalysts – optionally with 100- or 400-cell catalysts for maximum efficiency and rich sound.
New is the Engine Pack 1 : a targeted engine reinforcement with reinforced pistons, connecting rods and other components that make the drive fit for the 707 hp class – reliable and resilient.
Stage 4 is the result of consistent further development – a complete kit for maximum performance, robust technology and uncompromising propulsion.
If the OPF-TÜV downpipe is purchased and the software adaptation is carried out in-house, the kit can be registered in accordance with TÜV regulations.
IMPORTANT: There is no installation, no individual software tuning and no TÜV registration by HPerformance. This kit only represents the required hardware for the respective performance level. The shipping costs for sending in the turbocharger (if no new one is selected) are borne by the buyer!
Please note: Performance and acceleration values can be influenced by various external influences, fuels or additional hardware installed and ultimately the general condition (including mileage) of the engine. The values given are for guidance only and are not binding. With regard to legality and approval in the area of the StVZO we refer at this point to our general terms and conditions.

More than 700hp with 102 octane!
Stage 4 takes the RS3 8Y to a new level: 707 hp – legal . At its core is the TC Turbos X8 upgrade turbocharger , which, combined with targeted fresh air optimization , ensures maximum pulling power right up to the limiter. Improvements across the board give the RS3 a powerful, yet TÜV-compliant sound. Crucial at this performance level: Engine Pack 1 – a targeted engine boost that configures the pistons, connecting rods, and other internal components for the increased load and provides the necessary durability.
This level is the result of months of development work – including road approval, bench testing, and detailed optimization. HPerformance is currently the only provider that can achieve this level of performance legally and permanently .
Level 4 – for those who want the maximum without compromise.
