This listing is for a complete set of eight (8) Hitachi fuel injectors for 4.2L FSI Audi vehicles, like the B7 Audi RS 4. Hitachi is the OEM supplier of fuel injectors for such vehicles.

The OE Part Number for these injectors is 079906036D, which was superceded by 079906036AB. OEM Hitachi injectors are only getting more expensive and harder to find. These are listed for less than half of the last advertised price on FCP Euro (before they sold out). 

Originally purchased on July 2, 2022, these injectors were used for less than 2,500 miles. The injectors were removed in complete working order on September 20, 2022, which is when my engine was removed in preparation for a swap. The injectors have not been used since then.
