The full plug and play EKPM3 / EKPM2 cooler kit is designed specifically for E9X BMW's using an EKPM3 or EKPM2 fuel pump control module. This is recommended for anyone using a low pressure fuel pump that is larger than the OEM fuel pump.
Please note that if you have an HW06 + (Slim EKPM3), you must choose the HW06 option, as the pre-HW06 housings will not fit. If you have an M3, you must choose an EKPM2 style of cooler since the EKP Module has the same physical dimensions as an EKPM2.
10% of all proceeds from pink housings sold will be donated towards Breast Cancer research.
Installation Tips:

We recommend using Fuse #8 (2007+ E9X), which is the cigarette lighter fuse to power this. It is a 20 amp fuse, which you will just need to pull out and put it into the empty slot of the fuse holder that comes with the kit. Then you'll need to put that fuse holder into the now empty #8 fuse slot. This ensures that the fan will only turn on when the ignition in the car is turned on. You'll also need trim removal tools, as well as a 10mm socket in order to remove and re-install the EKP module. We recommend using the stock grounding point that's above the EKP module or the EKP module's mounting points as the ground. The ring terminal with the kit will fit either location. The whole installation should take you between 30 - 45 minutes.
We also offer a DIY kit that includes everything you'll need to create your own active cooling solution here: https://arcterminator.com/products/ekp-active-cooling-diy-kit
The cooler housing is designed to fit over the EKP module just like the OEM housing and fits with plenty of room in the stock EKP location. The housing is 3D printed using durable PLA+ or PETG, depending on the color choice. The full kit is printed and assembled in the U.S.A. by Arc Terminator LLC.

Why this kit exists:
The EKPM3 and EKPM2 have been shown to overheat and cause vehicle shutdown issues when larger fuel pumps that draw more current than OEM are used. This shutdown comes from critical components on the EKPM3 and EKPM2 overheating when larger current draws are coming from the fuel pump. The PNP kit comes with heatsinks for the most heat-sensitive and heat-producing components in the EKPM3 / EKPM2 to further increase cooling effectiveness. When paired with a potent 5015 blower fan that directs a large amount of airflow through the cooler housing, the EKPM3 / EKPM2 stays significantly cooler, which prolongs the life of the module. We also recommend anyone using a larger fuel pump than OEM to properly code their EKP module with Pro-Tool's built-in "Voltage Fix" feature. More information about this is in the FAQ section below.
FAQ:
Q: The EKPM2 has large electrolytic capacitors in the middle, will they block all the airflow?
A: The 5015 blower fan has plenty of power to push past, over and to the sides of the large capacitors and will effectively cool both transistors on the front of the EKPM2.
Q: This is 3D Printed, will it be durable enough to be in my car?
A: Yes, absolutely! Our housings are made from very durable PLA+ or PETG (depending on color options) and are designed to protect the EKP module from accidental impacts that may occur.
Q: How do I perform a "Voltage Fix" using Pro-Tool? (EKPM3 Only)
A: Check out this helpful guide from Skrillah416 on the Spool Street Forums: https://www.spoolstreet.com/threads/e60-fuel-pump-voltage-fix-coding-with-protool.5816/
Q: I'm a DIY'er, can I buy just the housing?
A: Absolutely! The housing alone is available here: Cooler Housing Only Also, if you've got a 3D Printer and you want to do your own thing, the STL file is 100% FREE for download here: https://www.thingiverse.com/thing:5478339
Other Information:
Depending on heatsink availability, you may receive heatsinks that look different than what is pictured. However, we have tested both variants of heatsinks and have not noticed any measurable difference in heat dissipation from either style.
Please note that the actual EKPM3 or EKPM2 Fuel Pump Control Module is NOT included with this kit and is only shown for fitment.

This product does not guarantee that your EKP fuel pump control module will not fail over time nor will this product fix any existing errors you may have with your vehicle.
Bought the ekp cooler kit with the new ball bearing fan. Can't hear it, so that's great. Easy PnP install with nice parts. Shipping was quick. Great company, will buy more stuff from them
As the title suggests, installation is fairly straightforward. Checked EKP running a WB450 LPFP and it feels lukewarm to the touch after a hard run. Hardest part of installation is getting the seat cushion that covers the EKP back into place properly, which is unrelated to the device itself. Great product!
Original EKPM3 kept overheating and shutting off at the worst times… leaving me stalled in dangerous traffic situations. Went to replace the module but realized the new part would just likely overheat and stall the car too (design flaw). Now with this “cooler” installed on the original EKPM3, I am able to drive the auto as hard and heavy in the heat as I please and it won’t shutdown. Thank you for improvising and improving on what is clearly an “oops” by BMW’s engineers.
Has been working great since day one 👍🏽 no issues
Awesome product very well made great packaging very easy to install with the instructions provided
