HPFP Internal Kit for Audi B9 3.0T / 2.9T

The Integrated Engineering HPFP Internal Kit is engineered to upgrade your Audi B9 3.0T or 2.9T engine's high-pressure fuel pump (HPFP). This kit allows for increased fuel flow, which is crucial for supporting hybrid turbochargers and advanced ECU tunes, including those designed for E85 fuel. The factory HPFP's internal volume can become a limiting factor when seeking higher horsepower and torque outputs. This upgrade features a significantly enlarged piston diameter (11.68mm compared to stock 9.92mm) and increased stroke volume, resulting in up to a 38.58% increase in fuel flow over the stock pump. A lightweight titanium retainer is also included. Installation requires specialized tools, and the HPFP Socket Tool is sold separately. While the process is straightforward, it involves fuel lines and necessitates meticulous care to prevent contamination in a clean environment. Experienced or professional installation is highly recommended, with an estimated install time of 2-3 hours. The kit fits directly into the factory pump housing without requiring permanent modifications. This kit is compatible with the Audi S4 (2017-2024, 3.0T), S5 (2017-2024, 3.0T), SQ5 (2018-2024, 3.0T), and RS5 (2018-2024, 2.9T), all within the B9/B9.5 chassis. Integrated Engineering offers a limited warranty of unlimited miles for 12 months.
