| PRODUCT OVERVIEW |
|
Introducing the all-new 2025 XS-POWER KO4-015 XLBF, the newest evolution of our legendary XLB turbocharger platform. This is not simply another K04 upgrade—it is an entirely different animal built for enthusiasts who demand maximum airflow, incredible spool characteristics and outstanding reliability. Built around an RS6 center housing rotating assembly (CHRA), paired with heavily modified K04-015 housings, the XLBF delivers airflow previously unavailable in a direct bolt-on longitudinal Audi 1.8T turbocharger. At the heart of the turbo is our massive 46.4mm / 62.3mm forged billet compressor wheel, substantially larger than a traditional K04-015 and capable of supporting over 295+ wheel horsepower with the proper supporting modifications. The XLBF utilizes an upgraded RS6 turbine and shaft assembly combined with proprietary machining to create one of the fastest spooling high-flow turbochargers available for the Audi 1.8T platform. Whether you're replacing a tired K03, upgrading from a standard K04, or building the ultimate street-driven 1.8T, the KO4-015 XLBF delivers unmatched performance while maintaining factory-style fitment. |

⭐⭐⭐⭐⭐ Built Like No Other K04 Upgrade
⭐⭐⭐⭐⭐ Built Like No Other K04 Upgrade If you're looking for the ultimate upgrade for your longitudinal Audi 1.8T, this is it. The KO4-015 XLB #2 features a massive 46.4/62.3 forged billet compressor wheel, upgraded RS6-style CHRA and turbine assembly, Forge-style actuator, and precision VSR balancing for exceptional reliability and performance. Spool is incredibly responsive, while the larger compressor delivers significantly more airflow than a traditional K03 or K04-015. Installation was straightforward, and the included gaskets and studs were a nice bonus. The quality, machining, and overall performance exceeded my expectations. For anyone wanting serious power without stepping up to a full custom turbo kit, this XLB turbo is an outstanding choice. Highly recommended! ⭐⭐⭐⭐⭐
