Porsche Panamera Turbo 971 Spool FX-350 High Pressure Fuel Pump Kit

The Spool FX-350 high pressure fuel pump kit for the Porsche 971 Panamera Turbo raises the fueling ceiling of the 4.0L twin-turbo V8 for bigger turbos and higher ethanol blends.

Why you need it

The stock high pressure pumps become a limit once you tune the Panamera Turbo for more power. The FX-350 has a larger bore than stock for about 90% more flow and runs at up to 35 MPa (350 bar) versus 25 MPa on the FX-200, which lets the injectors flow about 40% more fuel and shortens injection times. It is fully E85 compatible and plug and play with no cutting or splicing.

Fits

• Porsche Panamera Turbo (971, 4.0L twin-turbo 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 install hardware

Spool 10-micron filter

The included filter unit protects the high pressure pumps and injectors from contaminants without a pressure drop on the low side.

Good to know

The pump needs calibration changes, and they must be applied before the car is started with the pump installed. A custom tune is needed to get the full output. Spool supplies hardware, not tunes, but can share calibration details with your tuner. Adequate low pressure fueling is critical for the pump and injectors, so plan an upgraded low pressure fuel pump into the build. Professional installation is recommended.
