The full plug-and-play EKPM3 / EKPM2 cooler kit is designed specifically for E60 BMWs 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.

There are two versions of the kit, one with a relay and one without a relay. The relay kit is for those who would prefer to not put an additional load on their 12v outlet circuit due to using that circuit for something with a high load already. The non-relay kit will work perfectly for any normal use of the 12v outlet circuit and only adds up to 0.30 amps onto that circuit, which is very minimal.

For all M5s, you will need to use an EKPM2 kit as the EKP module is physically the same size as an EKPM2.

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.
