Spool Performance, 10 Micron fuel filter for BMW N54

Spool Performance in-line filter kit for BMW N54 models

Spool 10 Micron inline filter unit, BMW N54 engines
BMW N54 and (early) N55 are known to have decently solid HPFP fuel pump, but as the stage of tuning rises, the capacity of Continental rotary pump will eventually become a problem. Fuel pressure crashes especially in low- to mid rpm range under high torque, leading to misfires, problems with AFR and obviously a compromised power output.

While a solution such as Helix Overdrive unit offers a fix for this, the original filtration element inside the Continental pump quickly becomes a restriction.

For high power builds, it’s recommended to remove the OEM filter from the pump, and fit this high flow inline filter in your fuel line instead.

• 10 Micron steel filter, durable and efficient
• Compatible with E85
• Please note any previous changes made in your fuel line – this kit is designed for stock fuel line
