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.

                                Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.

                                Style: Ball, Size: Medium (Pack of 1)
                                I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing. He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.

                                This crunch ball was a Christmas gift for my 65lbs fur baby. It’s now mid April and he still loves it. He loves running after it and chomping down on it. It is still in good shape despite all the chomping it’s gotta . I highly recommend. He goes back to this toy agin and again! Great buy.
