FLOWN - BMW N55 Turbo Inlet

FLOWN is designed to reduce inlet restriction on higher-flow N55 turbochargers while remaining compatible with stock N55 PWG and EWG applications.

With a 62.5 mm internal diameter and compatibility with 2.5" silicone intake hoses, FLOWN provides significantly greater flow area than conventional N55 turbo inlets.

Compatible:

• OEM BorgWarner N55 turbo — PWG & EWG
• Pure 500 / Pure 600 / Pure 750* (standard 65 mm housing)
• Pure Stage 2 · VIV turbochargers
• Other unbranded N55 hybrids using factory 65 mm housing

Not compatible: Pure 750 with enlarged inlet, Shuenk, or any enlarged compressor housing.

As turbo airflow demand increases, the inlet becomes a restriction — especially with larger compressor wheels (Pure 600+). FLOWN increases inlet area to reduce pressure drop and give the turbo a cleaner path to air.

• Lower inlet pressure drop
• Reduced wastegate duty cycle
• Improved compressor efficiency
• Lower compressor outlet temperatures
• Increased high-RPM airflow & top-end power potential
