Plug-and-Play EKPM3 / EKPM2 Cooling Kit

For 2006–2013 BMW E90, E91, E92, E93 | Supports Aftermarket Fuel Pumps

If you're running an upgraded low-pressure fuel pump like a Walbro 450, 525, or 535, your factory EKPM3 or EKPM2 fuel pump control module can overheat and shut down under the increased electrical load—leaving you stranded. Our Arc Terminator Plug-and-Play Cooling Kit is the proven solution to this issue, offering active cooling that protects your EKP module from thermal shutdowns.

This kit is engineered specifically for E9X BMWs and includes everything needed to mount, power, and cool your EKPM module using a silent Noctua 60mm fan and precision heatsinks.

⚠️ NOTE: This kit is intended for vehicles without rear seats. The included 60mm fan will NOT fit behind OEM seat bolstering. For street cars, check out our DIY EKP Cooling Kit.

✅ Key Benefits

• Prevents Overheating & Shutdowns
  Keeps EKPM3 / EKPM2 modules cool under high current loads from larger fuel pumps.

• True Plug-and-Play Design
  No cutting, soldering, or splicing—fully reversible and clean install.

• Premium Silent Cooling
  Features a genuine Noctua 60mm fan for efficient yet ultra-quiet airflow.

• Precision Heatsinks for Critical Components
  Aluminum heatsinks target the highest heat-producing areas of the module.

• Built for Track & Performance Builds
  Ideal for stripped-interior cars and motorsports applications running high-power LPFPs.

📦 What’s Included in the Full Kit

• 1x Carbon Fiber PETG 3D-Printed EKPM Cooler Housing (PNP fitment)

• 1x Genuine Noctua 60mm Fan

• 3x or 4x Precision Aluminum Heatsinks w/ Thermal Tape (varies by EKPM version)

• 1x 2A Mini Blade Fuse

• 1x Alcohol Wipe

• 8x 4" Zip Ties

• 1x Pre-wired Fuse Tap Harness

• 1x Ring Terminal Ground Connector

🔧 Installation Notes

• Estimated Time: 30–45 minutes

• Tools Required: 10mm socket, trim tools

• Power Source: Use Fuse #8 (Cigarette lighter fuse on 2007+ E9X) for keyed-on power.

• Grounding Point: Use factory ground post above EKP module or module mounting bolt.

🔍 Fitment Notes

• Vehicle Compatibility: All E9X BMWs (2006–2013) using EKPM2 or EKPM3

• Choose Correct Housing:

  • HW06+ EKPM3 (Slim Style): Choose "HW06" version.

  • Pre-HW06: Choose standard EKPM3 kit.

💡 Not compatible with rear seat-equipped cars due to space limitations with the 60mm fan.

💡 Why This Kit Exists

BMW EKP modules are known to overheat when paired with high-output LPFPs. This often results in fuel starvation, drivability issues, or full vehicle shutdowns. The Arc Terminator cooling solution addresses the core thermal issues by:

• Dissipating heat from the MOSFET and half-bridge ICs (primary heat sources).

• Channeling constant airflow through the housing using a quiet yet powerful fan.

• Installing seamlessly into the OEM EKP housing location.

💬 FAQ

Q: Will the electrolytic capacitors block airflow in EKPM2 modules?
A: No. The fan is placed for optimal flow to the heat-critical MOSFETs and delivers more than enough cooling.

Q: Is 3D printed plastic safe for in-vehicle use?
A: Yes. We use carbon fiber PETG, a high-strength, heat-resistant material ideal for automotive interiors.

Q: How do I perform the "Voltage Fix" for EKPM3 modules?
A: Follow this Pro-Tool Voltage Fix guide from the Spool Street forums.

🛑 Important Notices

• EKPM3 / EKPM2 module NOT included.

• This product is not DOT-approved and is intended for off-road or motorsport use only.

• It does not fix pre-existing faults or prevent all forms of module failure.

• Use of high-current fuel pumps without this solution may cause module failure.
