Now Playing: Audi B8 RS4 Carbon Clean (+60HP) #audi #rs4 #carboncleaning #injectorcleaning

Regal Autosport 25 September, 2025 6:15 pm

Think carbon cleaning is a gimmick? Think again. In this video, we take a well-used Audi RS4 B8 and put it through a full carbon clean and injector clean to see just how much power is being left on the table by years of carbon build-up. The results? 556HP on the dyno - without any performance mods or tuning!

Timestamps:
00:00 Intro
01:35 'Before' Dyno Run
2:10 Carbon Cleaning Process
03:33 'After' Dyno Run
04:00 Power Results & Outro

Watch the full process as we:
✅ Show the carbon build-up before the clean
✅ Perform a thorough intake decoke / carbon clean / injector clean
✅ Run full before and after dyno pulls on our in-house dyno
✅ Reveal exactly how much horsepower and torque was gained

Whether you're driving an B7/B8 RS4, S4, or R8 V8, this video proves how much performance can be restored with just a carbon and injector clean - no expensive modifications needed.
