Installation Tips:

https://arcterminator.com/pages/e90-e92-e93-ekp-cooler-install-instructions

We recommend using Fuse #8, 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 ASA, ABS 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.

Use as directed, when needed, and you'll be good to go.
A must have if you have a need for a ZDDP additive. This won't fix your worn valve seats, leaking piston rings, seasonal depression or gout but it will improve the lubricating properties of a quality oil in a properly maintained motor for your longevity goals.

Buddy filled diesel skid steer with automotive gas engine oil. Used this to help.
We all know that guy who will buy a $65,000 machine and then only service it once a year with the cheapest oil on the shelf from Rural King or some other place with ultra cheap, home branded, questionably quality oil. Yep. That is my good buddy. So I go to the shop a couple weeks back and he is re-filling the skid steer engine with some ultra cheap, totally not to spec, gas engine oil. I question him and he states that it is perfect oil for the machine being 5W-30. I ask him if it meets the SAE ratings for the diesel, he repeats back that yep... it is 5W-30. So I go grab his New Holland book (C232 track skid steer) and look up the oil requirements, then I look at this junk oil, and I try to explain to him the SAE designations on the back of the bottle and the SAE requirements in the book. He looks at me like I have 3 heads and repeats that it is 5W-30, it is totally good. Someone.... kill me please! He has no clue what I am trying to explain. So I couldn't sleep knowing what he is doing, and I ran to Amazon to see if I can at least get zinc to add to the wrong oil and try to help the cam followers and rockers survive this next year. I found this. I ordered a few bottles and had them shipped to his shop, and I explained to him that these need to be dumped in to at least make an attempt in not prematurely wear the engine that likely is worth $20,000 or more! So the real question is, will he actually dump these into the machine, or will he toss them on a shelf never to be seen again? We may never know. But I bet next winter he will once again shop for the cheapest oil on earth to put in a machine that costs as much as some peoples home. He is who he is, you can never change that.

High quality replacement clips. Highly recommend.
I used these when replacing the headlight assemblies on my 2011 Honda CR-V. A few clips were already missing before I even started taking the bumper off, and of course a couple more didn’t survive the job. These fit perfectly and snapped right in with no issues. If you’re missing clips or break some while doing a repair, these are a simple fix that gets everything secured again. Very good deal.
