Product description:

The Stage 3 kit for the RS3 8Y significantly increases performance – with a focus on maximum power and pulling power right up to the limiter.

The heart of the system is the powerful TC Turbos X8 upgrade turbocharger in exchange , combined with the proven HP Sport Series intercooler and fresh air optimization for ideal supply to the charger.

New in this stage: additional injection nozzles that specifically ensure more injection volume at high loads – a must for increased performance in the upper speed range.

In combination with the selectable HP 4" OPF-TÜV downpipe or the racing version with 100 or 400 cell catalysts, a powerful, tuned overall package is created.

Level 3 is for those who don’t just want to feel performance, but want to push it to the limit – legal or track-ready.

A modular kit that specifically improves performance, sound and thermals – legal or uncompromisingly sporty.

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.

Core of TC Turbos X8!

With 620 hp and 710 Nm, Stage 3 delivers noticeably more performance for the RS3 8Y – especially where Stage 2 reaches its limits: at the upper rev range. The TC Turbos X8 upgrade turbocharger provides powerful boost pressure right up to the rev range, making the increased power noticeable at all times. It's supported by the HP Sport Series intercooler with air ducts , which ensures consistent temperatures under load.

The intake has been completely rebuilt: with the HP 4" aluminum turbo inlet , the matching HP 4" aluminum intake pipe (optionally in carbon) and a sports air filter insert for optimal air flow.

On the exhaust side, the HP 4" (101.6 mm) OPF-TÜV downpipe with underfloor catalysts reduces exhaust backpressure, improves thermal performance, and gives the vehicle a more emotional sound – fully TÜV-compliant. Stage 3 stands for linear thrust all the way to the top – noticeable, precise, and uncompromising.
