Never use lower octane than specified by the mode.- Max increases are based on APR's actual measured stock values and not those reported by Audi. RON = ROW Fuel Grades AKI = North American (RON+MON)/2 Fuel Grades.- Reported wheel figures measured using APR's in house dynos using SAE J1349 correction and an average of multiple runs for all figures. Crank figures are estimated based on the measured wheel figures and APR's engine dyno results. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications.
Results will vary heavily based on dyno conditions, especially with inadequate airflow. For the best results, APR recommends removing the intake snow screen.Audi S4/S5 (B8) (333HP)APR Stage 2+ Ultracharger91 AKI / 95 RON478 HP426 TQ+133 HP+97 TQAPR Stage 2+ Ultracharger93 AKI / 98 RON498 HP441 TQ+154 HP+112 TQAPR Stage 2+ Ultracharger100 AKI / 104 RON530 HP464 TQ+185 HP+135 TQAPR Stage 2+ Ultracharger104 AKI / 108 RON542 HP472 TQ+196 HP+143 TQAdditional DetailsFitment:.
