Spool IFX350 Upgraded DI Injectors +40% [S63 Gen 2]

Spool IFX350 Upgraded DI Injectors +40% [S63 Gen 2]

The Spool IFX direct injectors provide approximately 40% more flow than the factory injectors. They are intended for builds where the original injectors run out of capacity at high load and RPM while smooth idle and low-load behaviour remain important.

The extra fuel is delivered through the factory direct-injection system. Correct calibration changes are mandatory before running the engine with these injectors.

What the upgrade adds

• Approximately 40% more flow than the factory injectors
• Designed to retain smooth idle and low-load behaviour
• Suitable for gasoline and ethanol-based fuels
• Supplied as a flow-matched injector set
• Manufacturer-rated operation up to 390 bar

Injector size, high-pressure pump flow, in-tank pump capacity and calibration must be planned as one system so fuel delivery remains controlled across the full RPM range.
