Audi RS7 C8 Spool FX-350 High Pressure Fuel Pump Kit

The Spool FX-350 high pressure fuel pump kit for the Audi RS7 C8 raises the fueling ceiling of the EA825 4.0T so you can run bigger turbos and higher ethanol blends.

Why you need it

The stock high pressure fuel pump becomes the limit once you tune for more power. The FX-350 has a larger bore for about 90% more fuel flow than stock and runs at up to 350 bar versus 250 bar on the FX-200, which lets the injectors flow about 40% more fuel and atomize it better. It is fully E85 compatible and plug and play, with no cutting or splicing.

Fits

• Audi RS7 Sportback (C8, EA825 4.0T V8)

What's included

• 2 x Spool FX-350 upgraded high pressure fuel pumps
• Bosch-spec 10-micron high-flow fuel filter
• Upgraded fuel lines and installation hardware
• Spool ethanol content monitor kit with phone app (optional)

Good to know

Tune changes are required to run the FX-350 safely, and calibration details are supplied for your tuner. Proper low pressure fueling is critical, so plan a low pressure upgrade such as the EA825 PM5 low pressure fuel system. Professional installation is recommended.
