Looking good. Didn't know you could order with the shroud powder coated in black.
Don't forget to screw the cooler plug supplied with the kit. Why you may ask? Well I did with some consequences....
Drove around 400km on the highway yesterday in cool temperatures to begin with and finishing with around 30°c late afternoon. Regular driving with some start and stop conditions due to road works. Oil temps stayed between 105° and 108° constantly with water pegged at 93° without any variations.
Still need to experience some mountain road driving in M mode to really test the enlarged cooler's capabilities, but up to now I'm very happy with the kit.
On the fence with this (it looks awesome), but still haven't seen any clear indication that this solves our issues at the track (outside of the OP's own video). For my own purposes, I don't find the street driving results helpful.
Anyone else have good results on track with this? On a warm day, I'm in limp mode after a few minutes in S+. Can last longer in manual but have to upshift like crazy while waiting to pass, and have to be in higher gear than I want through turns. Currently deciding between investing more and more into cooling, or calling it quits and getting an M4...
Are you sure that the M4 doesn't have a plastic water pump?
The only BMW in our family (not an M4), had that, plastic thermostat housing, integrated transmission radiator in the engine radiator (with plastic end tanks) aaaand designed to run a 40% higher coolant pressure than other manufacturers.
Who measures coolant pressure, or reads in the specs what that is .....
When a BMW plastic radiator endtank lets go, it lets go with a bang.
In addition there was a radiator fan main electrical connector designed to be located in the chin of the car, where it gets submerged in puddle water. They probably thought they were sooo smart when they designed this with rubber insulating baffles.
Well, under the heat variations that happen often in the area under the front radiator, the rubber shrank, broke and the connector corroded.
As a result the radiator fan worked ... sometimes.
The replacement rsdiator fan also worked sometimes
After replacing the radiator fan sensor, it also worked sometimes.
Until I found this, corrected their design by cutting off the damn connector, soldering the wires together (with a slack coil), and shrink wrapping the soldering.
Then tha radiator fan worked always.

Do you only use the car on the track? I'm sure limp mode is an inconvenience if you track it constantly, but for that to be a deciding factor to get rid of the car....lol.
Thanks, I did the blocker plate. Didn't seem to help me avoid limp mode. Although I did seem to get an improved throttle response, which was nice. Anyway, after hearing a lot of good things about the blocker plate but not seeing any benefit myself, I'm hesitant to jump on this oil cooler unless someone who tracks regularly reports a noticeable improvement.
Yeah, block off plate did jack for me as well. You need a larger center cooler and if you're not in a hot climate sitting in stop and go traffic often, ditch the arch cooler fan since it's extremely restrictive.
If you want to go a step further, which involves removing the timing case cover, you can cut the spring in the mechanical thermostat for your oil cooler in the block. It's still very restrictive when in the full open position but this can also cause the oil to take longer to warm up for daily driving.
Unfortunately it still needs to function well in hot stop and go traffic, but I'll definitely keep that option in mind if it ceases to be a daily driver.

Time to time I usually join a group of friends for some spirited driving. Stock oil cooler was hitting really high temps about 260s till i started to notice shifts were bogging. Can’t really have fun when you can’t keep RPMs above 5000 rpm for more than 5 minutes. Got this oil cooler and went Thunderhill 5 mile weather was about low 80s, oil temps never got above 250. In other words, it works.
Unfortunately it still needs to function well in hot stop and go traffic, but I'll definitely keep that option in mind if it ceases to be a daily driver.
When I upgraded to this cooler I removed my auxiliary cooler fan with no adverse affects and have been it stop go traffic in 35C heat and never went over 107C.
Before this cooler and fan removal I constantly saw up upwards of 115C with 112C being the norm in peak hour traffic.
I've been meaning to come back to this thread. The need for a larger cooler arose from driving in traffic in scorching summer temps in NYC and spirited driving on backroads. Also the car would make it out to an occasional track day so wanted to be protected on that front. The oil temps would climb to 260-270F on the regular, and I've seen almost 280F a couple of times. Not a comfortable operating temp and something needed t obe done.
Ordered Sven's cooler over the winter and installed it in March. Now that we are almost through summer and went through some very hot humid days her in NYC, I can say this oil cooler definitely works and the temps have not exceeded 255F. Normal operating temps are also much lower on average, so the car in general runs cooler. Having said that, we haven't had it out on track for a proper trashing yet so I cant report on that. However, there is definitely a noticeable difference in temps on average as I mentioned so I would be confident track temps would not be a problem. This went from a constant worry on hot days to to even being in the back of my head.
Nice pictures! I always like this air duct when I see it mounted. Especially painted in black or powder-coated.
And very good that you disassembled the fan! With my oil cooler it’s no longer necessary.
My oil cooler is larger than the front one on the Black Series. If you add the original wheel arch cooler, you have exactly the same cooling surface as the Black Series, because it has a larger wheel arch cooler.
This balances out and you have the same cooling surface. And there is no fan mounted on the Black Series either.
Any ideas on how to install a heat exchanger with this oil cooler? I’m thinking I’m going to have to do away with the bracket but I’d like as much flow as possible.
What about the latest people, are you happy with your new oil cooler? What are your experiences?
Haven't had time to put on a review since I installed it around 6 months ago.
Previously during normal drive here in normal traffic, the oil temp will typically hit 110-115C.
Ever since I installed the oil cooler, I have never seen my temp at 110 during normal drives. Its usually around 100-103C now.
Would say this is one of the best mod to do.
Really happy with this oil cooler.
For a real world review, I did some mountain passes recently in perfect weather and traffic conditions. WOT and very often close to the red line in each gear. Didn't see the oil get over 110°c but the real positive thing I saw was that when driving normally after, the temperature would fall back down to 105°-108° very quickly. I'm very happy with this upgrade. Thanks Sven
So it seems like the drain plug on the new cooler is on the bottom and you drill a hole in the under tray for access. Does the drain plug on the new cooler take the same washer as the drain plug on the stock oil cooler? As it seems that washer is supposed to be replaced each time on the stock oil cooler.
thanks
