We are pleased to announce the release of our Supercharger Cooler System for the Audi B8.5 S4. Our engineers spent countless hours data logging the S4’s supercharged 3.0 TSFI engine to give you the absolute best cooling system using the highest quality components available today. Based on your feedback from the B8 S4 system, we revised the pump wiring harness on both systems so no wire splicing is required, it’s all plug and play! Check out the link below for the full product description, images, tons of data logging and pricing!
