Description
CSF F1X M5/M6 and F9X M5/M8 High-Performance Engine Oil CoolerThe original OE oil cooler from BMW is an all metal design which would make you think it would be fairly robust. However, there are several weak spots in the design that make it far less durable than it could be. The CSF design resolves these issues with more robust materials and reinforcing weak points. At first glance, the original BMW OE oil cooler appears solid due to its all metal construction. However, design weaknesses make it far less durable

Great price, but don't stack multiple wires
Size: 300A
I used this as a junction point on a 1 gauge wire. I added an 8 gauge wire to one side, and the cover would not seat. I had to bend and maneuver the ring terminals to make the cover catch. For the price of the items, if used without any secondary wires attached and interior use only, this is an unbeatable deal.

I was not expecting these to be this nice. You just can't beat the value. They look great and feel like they will hold up a long time. I definitely recommend!
