The IE HPFP Internal Kit is designed to enhance the high-pressure fuel pump in Audi B9 3.0T engines with an expansive piston and cylinder design, maximizing fuel delivery capabilities for hybrid turbos and Stage 1/2 Plus ECU tunes. Meticulously crafted using premium-grade components and subjected to an industry-leading quality control process, this upgrade ensures unparalleled reliability. Users can significantly increase their fueling overhead, allowing for worry-free operation of the 6-cylinder turbocharged engine.

ADDED DISPLACEMENT:

The HPFP (High-Pressure Fuel Pump) plays a crucial role within the B9 3.0T platform's direct injection (DI) system, ensuring the injectors receive an exceptionally high-pressure fuel supply, exceeding 2900psi. However, when pursuing turbo upgrades or utilizing ethanol fuel, the stock HPFP internal volume can become a limiting factor in power increase.

FLOW TESTING:

The IE HPFP Upgrade Internals are meticulously designed to offer the largest size within the B9 3.0T pump body, ensuring optimal performance. One of the key enhancements is the enlargement of the factory-installed 9.92mm internal pin, which has been meticulously increased to 11.68mm. This modification significantly augments the stroke volume from 448mm^3 to 621mm^3, leading to an impressive maximum gain of 38.58% more flow than the stock configuration. This remarkable increase in flow ensures a substantial improvement in fuel delivery, allowing for enhanced engine performance and power output.

The IE HPFP Upgrade Internals undergo a meticulous manufacturing process to ensure precision and reliability. Each piston and cylinder is CNC machined to exacting sizes, followed by an accurate in-house assembly. The components are carefully measured as a matching set, and tolerances are hand-verified using specialized measurement tools, ensuring accuracy down to an astonishing 0.00005 of an inch. This rigorous quality control process guarantees that the HPFP internals function flawlessly and are highly reliable.

The commitment to these extreme manufacturing and QC processes has solidified IE's reputation as a leader in HPFP reliability. As a result, IE's HPFP designs have become the preferred choice for those seeking worry-free operation and dependable performance, making them a popular option among enthusiasts and professionals alike. Whether pursuing performance upgrades or looking for enhanced fueling capabilities, IE's HPFP Upgrade Internals assure exceptional quality and consistent functionality.
