Integrated Engineering's 2021 B9.5 Audi S4
The Perfect Daily B9.5 S4 build series by Integrated Engineering documents the journey of transforming an Audi B9.5 S4 into a highly capable, enthusiast-driven daily performance sedan. Across three episodes, the iE team takes viewers from the initial introduction of the platform and build goals through the thoughtful installation of key performance upgrades tailored for the turbocharged 3.0T V6 including high-flow intake and exhaust components, intercooler and ECU tuning enhancements, and other bolt-on hardware designed to improve power, throttle response, and overall driving engagement. In the finale, the fully upgraded B9.5 S4 hits the track for roll racing, showcasing the results of the integrated modifications and tuning in a real-world performance environment that highlights more refined power delivery, boosted performance, and a more spirited driving experience ready for everyday use.
