Porsche Cayenne Turbo 9Y0 & 9Y3 Spool FX-350 High Pressure Fuel Pump Kit
The Spool FX-350 high pressure fuel pump kit for the Porsche Cayenne Turbo (9Y0/9Y3) raises the fueling limit of the 4.0L twin-turbo V8 for bigger turbos and higher ethanol blends.
Why you need it
The stock high pressure pumps hold the Cayenne Turbo back once it is tuned. The FX-350's bigger bore gives about 90% more flow than stock, and it runs up to 35 MPa (350 bar) versus 25 MPa on the FX-200, which lets the injectors flow up to 40% more fuel with shorter injection times and better atomization. It is fully E85 compatible and plug and play, with no cutting or splicing.
Fits
- Porsche Cayenne Turbo (9Y0)
- Porsche Cayenne Turbo Coupe (9Y3)
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
Good to know
Calibration changes are required to prevent damage, and Spool supplies calibration details to your tuner. A low pressure fuel upgrade is recommended so the pumps always get enough supply. Professional installation is recommended.
