I just picked up my Audi RS3 FL Sedan with OPF from HPerformance. I got the 4-inch exhaust system and a Stage 3 upgrade. I’m just super happy with how it drives and, above all, how brutal it sounds despite the OPF. Everything worked great—I can really recommend it to anyone who loves their five-cylinder engine!!
The Stage 1+ performance upgrade , delivering 510 PS and 665 NM, includes our in-house manufactured Sport Series intercooler, our new OEM+ (closed) 4" (100 mm ) intake ( variant selectable) starting from the turbocharger, and a replaceable plate filter. The intercooler significantly improves intake air temperatures, which not only delivers noticeable power gains but also greatly enhances power reproducibility. The intake system facilitates airflow and reduces vacuum pressure before the air enters the turbocharger. This combination not only enables higher power output but also ensures that power remains consistently available. The intake noise—but especially the nature of the power delivery and its consistency—clearly distinguishes this stage from Stage 1.
In addition to the hardware mentioned above, our service naturally includes fuel-specific tuning on our in-house all-wheel-drive test stand .
