PRODUCT INFORMATION

THE ULTIMATE COOLING SOLUTION FOR BMW F8X M3, M4, & M2 COMPETITION


The BMW F80 M3, F82/F83 M4 & F87 M2 Competiton are still regarded as some of the best performance platforms available. BMW’s S55 Motor has amazing potential for power and there are countless performance parts available for it. However, like most production engines, the S55 doesn’t come equipped from the factory with sufficient cooling capabilities to cope with added power or even prolonged performance driving. CSF have designed a full line of S55 cooling options to help you get the most out of your BMW F8X. The CSF Charge-Air-Cooler, Heat Exchanger, and Transmission Cooler will keep you ahead of the competition.


BMW F8X TOP MOUNT DUAL-PASS CHARGE-AIR-COOLER


The S55 suffers heavily from heat soak. Many tuners witnessed this early on after doing multiple dyno pulls and seeing significant drops in power after each consecutive pass. Many F8X owners experienced the same loss of power on the track as the engine just could not cool off during laps. The solution is two fold: The Charge-Air-Cooler & Front Mount Heat Exchanger work together to keep the intake temps down and power up. The factory units simply cannot dissipate enough heat to keep up with prolonged performance driving. Our Charge-Air-Cooler boasts a core size that is 60% larger, greatly increasing the capacity for heat transfer from the hot charge air coming from the turbos. Paired with the Front Mount Heat Exchanger the system is able to maintain lower intake temps and keep your BMW F8X’s power up.

The CSF Dual-Pass Top Mount Charge Air Cooler is a direct replacement for BMW part number 17517846235.

FEATURES

  • World’s 1st cast end tank designed top mount charge-air-cooler for the BMW S55 engine.
  • Multiple air dividers cast into both the hot/cold side end tanks for optimized air flow through the custom designed CSF liquid-to-air intercooler core (CFD analysis and testing completed to ensure optimal performance).
  • 60% increase in core size compared to the OEM cooler.
  • Left/right, cross-flow, dual-pass core configuration with 2-stage water cooling for maximum efficiency and intake temperature reduction (vs. OEM single-pass vertical-flow design).
  • Designed with 3D scanning / rapid prototype technology to ensure precise fitment and maximum surface area utilization.
  • “Drop-in fit” design for an easy & quick plug-and-play installation, complete with OEM style “Quick-Connect” water connections and sensor ports.
  • Finished with a Raw Aluminium finish (CSF8082R) or a professional "Crinkle Black" powder coat finish (CSF8082). Optional finishes also available for an additional cost.

                                Well this product works. At first I thought maybe the Caribbean sun wasn’t as bad as people said since I was in the sun for 4 days wearing this sunscreen and hardly had tan lines, then I tested my theory for 1 day with another brand and got a sunburn. I took star off (would really only do a half if it allowed) for when you go in the water or if you sweat there is a bit of white residue that it leaves. But for sun purposes, if you want protection, I highly recommend.

                                A must have for superior sun protection!

                                Neutrogena Beach Defense SPF 50 is an absolute game-changer when it comes to sun protection. Whether you're relaxing at the beach, swimming, or enjoying an outdoor adventure, this sunscreen provides broad-spectrum protection that effectively shields the skin from harmful UVA and UVB rays. One of its standout features is its lightweight texture, it glides effortlessly onto the skin without feeling greasy or heavy. Unlike some sunscreens that leave a sticky residue, Beach Defense absorbs quickly and smoothly, making it ideal for both face and body application. Another major plus? Water resistance! This formula stays put, even after swimming or sweating, ensuring continuous protection throughout the day. And despite its strong defense against the sun, it feels refreshing and comfortable on the skin, making reapplication a breeze. I used it during a vacation in the Dominican Republic, and me and my family enjoyed it. My 5 years old girl has been protected from the sun all the time. If you're looking for reliable, effective, and easy-to-use sun protection, this sunscreen is an excellent choice. Highly recommended! ☀️👌

                                We love the Aveeno Soothing bath treatment in our house! It works so well when my son is dealing with allergy flare ups, itchy skin or rashes. The oatmeal bath is very calming and gentle on sensitive skin, and helps relieve redness and irritation quickly. After soaking, his skin always feels softer and less irritated. Definitely a must have to keep on hand during allergy season.
