PRODUCT INFORMATION

THE ULTIMATE COOLING SOLUTION FOR THE BMW S58 ENGINE


The S58 motor is a tuners dream capable of incredible power on stock internals and bolt on modifications. However, power always comes at the cost of producing more heat. CSF offers a variety of cooling systems to keep your temperatures in check. The Cooling Experts at CSF design and manufacture the ultimate cooling solutions for BMW.


BMW G8X M3/M4 HIGH-PERFORMANCE HEAT EXCHANGER


Arguably one of the hottest German performance vehicles of the decade, the G8X M3/M4 has quickly become a favorite among enthusiasts and race teams alike. Like many BMWs, the S58 motor has some heat issues under heavy driving conditions when modified. CSF has been working tirelessly for the last year on a complete suite of industry leading cooling products for the G8X platform. Now, with over 9 months of development and testing, CSF is pleased to announce the release of its highly anticipated high-performance G8X M3/M4 Heat Exchanger (CSF #8215) for both 6-speed manual (6MT) & ZF8 automatic transmissions.

CSF has worked closely with race teams throughout North America such as Studio RSR, Art of Attack, and Velocity Performance as well as premier dealer Precision Sport Industries throughout the prototyping and development process. The feedback gathered from daily driving, track days, and competitive drag racing events has lead to the best possible iteration of the Front Mount Heat Exchanger.

OEM COOLING COMES UP SHORT

When the new M3/M4 was released in late 2020, it didn’t take long to see them hit the track. CSF’s Engineers and Motorsports department was in attendance for some of the first track days that local R&D Partners & Premier Dealers Studio RSR and Art of Attack took their new G8Xs to.

While in stock form, the G8X’s factory cooling system does a decent job keeping up with the cooling demands. While this was true of the car in factory spec, those results changed when the cars were modified and started pushing more power. CSF quickly observed issues with heat soak in the charge-air system. This overheating of the intercooling system causes a spike in Intake Air Temperatures (IATs). Subsequently, the ECU started pulling timing which decreases power output. In extreme cases this can also send the car into limp mode. This problem became even more prevalent as testing continued into the hot summer months.

HOW CHARGE-AIR COOLING SYSTEM WORKS

CSF’s industry-leading reputation and deep knowledge of high-performance BMW cooling systems allowed its engineers to immediately identify the cooling weak spots on the S58 engine. The engine is very similar to the B58 in the A90 Supra and G-Series BMW 40i models. Both feature a liquid-to-air charge cooler manifold paired with a front mount heat exchanger (water radiator). The Heat Exchanger cools the fluid cycling through the charge cooler, dissipating heat from the system.
Please see photos for further detail on these points.
Because the charge cooler is built into the manifold, it’s extremely expensive to replace with a high-performance unit. While CSF has developed a high-performance billet charge-air manifold for the S58 Motor (CSF #8233), the heat exchanger is still the most cost effective way to bring down charge-air temps. The Front Mount Heat Exchanger is responsible for removing heat from the chair-air cooling system and is now recommend as a critical bolt-on upgrade.

DESIGN, DEVELOPMENT AND TESTING

With well over 100 track hours worth of testing and thousands of miles on the road, you can be assured that the CSF’s new High-Performance Front Mount Heat Exchanger has been thoroughly tested and vetted.

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 (#CSF8221).

The two included Black Rock Guards offer full protection for the heat exchanger (above and below the crash bar), especially when paired with aftermarket “open face” race style grilles. These grilles have become quite popular for performance and aesthetics, and keeping your heat exchanger safe from debris is very important.

FITMENT

The CSF Front Mount Heat Exchanger is a direct replacement for BMW part number 17118095283. Suitable for G8x M3/M4 models with 6MT or ZF8 Auto (incl. Competition).

                          My Favorite Face Mask for Hydrated, Glowing Skin
                          Scent: Collagen, Size: 4 Count (Pack of 1)
                          I’ve tried a lot of face masks over the years, but the BIODANCE Bio-Collagen Real Deep Mask has easily become my favorite. Every time I use it, my skin feels incredibly hydrated, smooth, and refreshed, and the results last much longer than I expected from a single mask treatment. One of the things I love most about this mask is how deeply moisturizing it is. After wearing it overnight, my skin looks noticeably plumper and feels soft and nourished. Instead of just giving a temporary boost, I’ve found that the healthy glow lasts well beyond the next day. In my experience, my skin maintained a radiant, hydrated appearance for nearly two weeks after use, which is something I haven’t experienced with many other masks. The hydrogel material feels comfortable on the skin and stays in place well throughout the night. When I remove it in the morning, my skin looks brighter, more refreshed, and noticeably more hydrated. I appreciate that this mask feels like a true self-care treatment rather than just another skincare step. Whether I’m preparing for a special event or simply giving my skin some extra attention, this is the mask I consistently reach for. The fact that it comes in a multi-pack makes it even better because I always like having one available when my skin needs a boost. Overall, this is one of the few skincare products that I continue to repurchase because I genuinely notice a difference. If you’re looking for a mask that delivers intense hydration, plumping benefits, and a beautiful long-lasting glow, I highly recommend giving this one a try.I’m

                          Scent: Collagen, Size: 4 Count (Pack of 1)
                          I’ve tried SO many sheet masks and this collagen one is genuinely one of the best. My skin looked insanely hydrated, smooth, and glowy after just one use. It fit my face really well, stayed soaked the entire time, and didn’t leave that sticky feeling afterward. The next morning my skin still felt soft and looked brighter. Perfect before events or whenever your skin needs a reset. Definitely repurchasing!!

                          The first 3 pictures were taken after the first hour and a half. The second 3 pictures were taken at 2 hours. The mask had a hard time dissolving underneath my eyes and around my chin area mostly but everywhere else it hardened within the first hour or so. I will try to wear it for longer than 2 hours next time. To see if that changes, but my skin feels really nice right now. It's a little sticky, but it looks healthy and has a nice glow. Application is easy. I love that its separated into 2 parts. Doesn't fit well around the nose between the eyes and doesn't cover my entire face but its a great mask. I tried the caviar one this time. I have the collagen ones as well but these have better reviews. They seem to work effectively, for a nice glow and self pamper session.

                          I’ve been really impressed with this Bio-Collagen hydrogel mask! It feels incredibly cooling and soothing on the skin, especially after a long day. The overnight wear is a huge plus—you wake up with your skin feeling noticeably more hydrated, plump, and smooth. It doesn’t feel heavy or sticky, and it stays in place better than most sheet masks. After a few uses, I’ve noticed my skin looks more refreshed and even, and my pores appear a bit more minimized. It’s a great option when your skin needs a little extra boost or before an event when you want that “glow.”

                          Scent: Collagen, Size: 4 Count (Pack of 1)
                          I was honestly impressed with this mask! It feels super soft, cooling, and refreshing while wearing it. The jelly texture makes it feel really hydrating and luxe, like a mini spa night at home. My skin looked smooth, plump, and GLOWING the entire next day after I took it off. Like… noticeably radiant. I also have sensitive skin, so I was a little nervous trying it at first, but I didn’t have any irritation or reaction at all. My skin felt calm, hydrated, and refreshed afterward. One thing I actually liked was that the mask was easy to customize a little. I have a nose piercing, so I just tore a small piece near my nose so it would fit comfortably without irritating it. The material held up perfectly, so that was a nice bonus for anyone with piercings or who just needs a better fit in certain areas. My only complaint is the “sleep in it” part of the instructions. I personally don’t see how that’s possible 😅 The mask stays pretty moist and jelly-like the whole time, so it felt uncomfortable to lay down in and I kept feeling like it would slide around. I ended up just wearing it for a while before bed instead. Overall though, the results were worth it and I’d definitely use it again for the glow alone!
