For over 40 years, Mosselman Turbo Systems has delivered high-end performance parts engineered and manufactured in the Netherlands — specializing in BMW and Mini applications. From tuning software to turbochargers and oil cooling systems, their offerings empower enthusiasts to tune confidently and reliably.

What Mosselman Offers

• ECU Tuning & iTronic Modules
  Unlock the full potential of your vehicle with stage-specific ECU remaps and iTronic external tuning modules that retain factory ECU and allow plug-and-play install with minimal fuss.

• Turbochargers & Upgrade Kits
  Engineered in-house for improved airflow and faster spool, Mosselman turbos like the N20 stage-1 unit offer serious performance gains without sacrificing reliability.

• Oil Cooling Upgrades
  Beat heat with single or twin oil cooler setups and thermostats that lower operating temps for sustained performance under pressure.

• Safety & Engine Hardware
  For high-tuned engines, items like the S55 crank hub upgrade improve engine longevity and timing confidence during high-stress driving.

Why Mosselman Stands Out

• BMW & Mini Expertise
  Their focus is unmatched—Mosselman designs everything specifically for these platforms, offering tailored solutions and unmatched quality.

• Proven Performance Packages
  On models like the BMW M5 F90 and M3 F8x, Mosselman offers staged performance kits that have been dyno-tested, delivering clear horsepower and torque gains.

• All In-House Engineering
  From turbo design to ECU software, Mosselman controls every detail—offering quality and confidence for every part shipped.
