OE Ultimate Under Supercharger Kit (Audi EA837 B8, C6, and 4L 3.0T Gen 1)
Vorsprung Autowerk Ultimate Under-Supercharger Service Kit (Gen 1 EA837 B8, C6, and 4L 3.0T)
Don’t pull the supercharger twice. Do it once, and do it right.
If you are removing the supercharger on your Gen 1 Audi 3.0T to replace a failing thermostat or PCV valve, replacing the rest of the critical "under-blower" components while you're in there isn't just recommended—it's mandatory.
The factory plastic cooling components are notorious failure points that leave drivers stranded and facing massive labor bills. The Vorsprung Autowerk Ultimate Under-Supercharger Service Kit bulletproofs the valley of your 3.0T. We've taken the guesswork out of this heavy-duty maintenance job by assembling the highest-quality OEM, OES, and upgraded metal components on the market. This is the most complete kit on the market!
Say goodbye to cracking plastic housings and leaking seals. This kit is designed for enthusiasts who demand peak reliability for their daily drivers or stage-tuned track weapons.
