IE's HPFP internals upgrade kit for the Audi 3.0TFSI Supercharged engines is perfect for the DIY user looking to upgrade their factory-equipped HPFP pump body with new higher flowing internals. These USA-engineered and manufactured parts will reliably transform your stock pump housing into a high-flow fuel pump for use on dual pulley ECU tunes to provide enough flow for ethanol fuel blends. The 11.67mm piston is the largest sized diameter possible within the fuel-pump body.
