Spool Performance is known in the automotive community, particularly among enthusiasts of turbocharged vehicles. The company has garnered attention for its high-pressure fuel pump upgrade solutions for various cars, especially in the BMW community. These upgrades are crucial for vehicles that have been tuned to produce more power than stock, as they often require increased fueling to maintain safe and optimal performance.

Spool Performance's products address a common bottleneck found in many tuned vehicles – the high-pressure fuel pump's (HPFP) inability to deliver the necessary fuel volume. Their products aim to provide a solution that ensures sufficient fuel delivery for high-performance applications.

August 24th, 2023 - Spool Performance is proud to introduce our upgraded DI injectors for the S58 platform. The IFX 350 is the highest flowing S58 injectors on the market and is carefully sized for the S58 engine to keep stock-like idle and low load characteristics while allowing 30% more injector flow at high load and high rpm conditions. The injectors have undergone rigorous testing over months on our different test cars and have been perfected before release.

Flow: 30% over stock DI injectors

Pressure: Capable of flowing at up to 390 bar pressure

Tune changes are required for running these injectors. Spool Performance will provide full calibration support for the same over all existing tuning platforms for the Gen2 B58

The injectors are covered by our warranty for a period of 1 year from the date of purchase.
