CSF Cooling has officially released their High-Performance G8X M3/M4 Heat Exchanger! The S58 platform loves to run hot under extensive driving and this is the perfect fix. CSF has been testing this system for the past 9 months and we personally have had this unit on our G80 for the past 5000 miles. We have taken it through the mountains of Georgia, the heat of Florida and even the deserts of California. This unit has stood up to everything we have thrown at it even through some of the harshest of conditions. This heat exchanger fits both the 6-speed Manual and the 8-speed automatic and features two protectant shields.

The CSF Heat Exchanger features a 2-Row (vs OEM single row) Core that is 42mm thick with CSF’s Exclusive B-Tube Technology. Increasing the size of the core and end tanks adds to the overall volume of the system which helps absorb more heat. The more efficient core not only helps dissipate more heat from the system, but also provides better airflow into the radiator that sits behind the heat exchanger. For vehicles equipped with the ZF8 Automatic Transmission, the heat exchanger core specifications were design concurrently with CSF’s new Race-Spec Dual Core Transmission Oil Cooler.

CSF makes great products that are automotive works of art that are very functional.

Had one on my E36 M3 and my E90 335i.
Great products.

BMW radiators should be considered consumables that last about 80k miles. These are not.

[curtdragon]

I bought one of their radiators for my Audi. Great products. Adding this to the list

Where is the data to show improvement over the factory setup? By how much is it better?

[HP Autosport]

Can't go wrong with CSF. Great company and great products!

[moproblems]

TIL That there is no freon/air ac condenser. Just a freon/fluid condenser that drops heat into the cooling system

Most important parts left out lol..

Asking the real questions here.

Long thread about this for F8X. I don't believe the data was ever released there, so I wouldn't hold my breath :

Why not have the rock guard cover the entire grill? Doesn't make sense to have it 1/3rd open since you're still risking rocks in that opening.

By this much 😉

You're not, actually.. because that part sits behind the large cross beam and impact risk is probably negligible at best.

It has the rock guard in place as well.

That makes sense. Forgot about the cross bar.

Are we to believe this actually provides measurable performance gains with no track data to back it up? Sounds like the car was taken on a few road trips in hot climates. A Honda minivan can do that.

Sorry, but sounds like more aftermarket money grab to me. Pretty sure the engineers at BMW Motorsport know how to handle heat by now…

I imagine over a long period of wide open throttle you will see an improvement in cooler intake temps, how that translates to a hp increase is anyones guess. But if I were doing 30min tracking sessions often I'd get this.

Literally everything CSF releases has no data. Just look at their S55 top mount heat exchange thread. Years of asking for data and none provided. CSF Cooling

Exactly. My understand is the g80's (and f80's) cooling system is nothing short of absolutely stellar. You can take a stock one to the track in August, beat the absolute piss out of it for hours on hours, and you won't run into ANY heat soak issues/timing being pulled issues whatsoever.

I was reading the text about these products from CSF and it was something along the lines of "One of the weak points in the new G8X chassis is the cooling system". At that point I was like holy shit this is a money grab. Con artist vibes.

Maybe if you big turbo the car then I could see how this might be needed. But stock form/up to stage 2+ this is totally worthless... especially if there is ZERO data provided.

Attached to this URL https://csfrace.com/new-csf-high-per...eat-exchanger/ there is a great explanation of exactly how this setup upgrades the S58 Cooling process!

The middle aspect of this heat exchanger is blocked by the OEM crashbar/crossbeam. The added shields are there to protect from small debris and for those who choose to run alternative front grills.

Total miss by CSF. They could've put some CF bits on this and a badge saying "Art of Cooling", and they would've struggled to keep up with demand.

[edwinm3]

is this a must do replacement on the new G8X?
