When the factory heat exchanger runs short on capacity, coolant temps climb, intake temps follow, and the car heat soaks. Of the two main S55 cooling upgrades, the heat exchanger is widely considered the more important, so if you only do one piece, start here.

While this was true of the car in factory spec, those results changed when the cars were modified and started pushing more power.As with most performance vehicles, power adders were some of the first products to be released for the new G8X platform. Bolt-on upgrades, software tunes, and upgraded turbos are all great for speed, but start to create heat issues. Any time you add power to your car, you naturally increase the amount of heat the engine produces.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 #8221).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.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. \u003c\/span\u003e","brand":"CSF","offers":[{"title":"G80 M3","offer_id":46767380529452,"sku":"csf8215","price":699.0,"currency_code":"USD","in_stock":true},{"title":"G82 \/ G83 M4","offer_id":46767380562220,"sku":"csf8215","price":699.0,"currency_code":"USD","in_stock":true},{"title":"G87 M2","offer_id":46767380594988,"sku":"csf8215","price":699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0287\/7774\/2435\/products\/ae1b05e33b3af263b2f7749e0ea5a628.jpg?v=1680229206"},{"product_id":"csf-s58-charge-air-cooler-manifold-raw-billet-g80-m3-g82-g83-m4","title":"CSF S58 Charge-Air Cooler Manifold (Raw Billet) - G80 M3 | G82 \/ G83 M4 | G87 M2","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe S58 is not short on power, it is short on cooling.

Pressure drop actually falls to 1.10 PSI from the OEM 1.22. Across 8 consecutive full throttle pulls, post cooler intake air temps rose only 21.2 degrees F. Independent dyno testing by MotoIQ at GTP Motorsports on a G82 M4 showed 20.6 wheel horsepower and 20.4 lb ft, with charge temps averaging 61.85 degrees F cooler, and the core held up past 45 PSI where the factory unit gives up.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe B version adds a Cerakote thermal dispersion black coating, which is not just cosmetic.

Manual cars do not use this cooler, and the M2 Competition with the S55 is a different part, so confirm your engine and transmission before ordering. Installation is a true drop in that reuses every OEM attachment point, including the factory oil line quick connects, mounting brackets, and shroud and ducting. No modification, no additional hardware, and no tune.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eWill not fit F87 M2 Competition with S55 motor.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eFITMENT\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e- F87 M2 (N55) \u003c\/p\u003e","brand":"CSF","offers":[{"title":"Default Title","offer_id":53665717846316,"sku":"csf8103","price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0287\/7774\/2435\/files\/c5968f9dd120e6a08f4e561d2256e165M.jpg?v=1786308009"},{"product_id":"csf-n55-radiator-f22-2-series-f87-m2","title":"CSF N55 Radiator - F22 2-Series | F87 M2","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe N55 makes easy power, and every common mod on the platform adds heat the factory radiator was never sized for. The stock unit uses plastic tanks and a crimped seam that eventually leaks, and coolant temps climb enough on track to pull timing well before anything mechanical is at risk. This CSF is a full aluminum replacement built to end both problems in one part.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eIt uses a two row 42mm dual core with CSF's B Tube technology, where a seam brazed inlet down the middle of each tube splits the flow and adds roughly 15 percent more heat transfer surface than a conventional oval tube in the same space. The fin pack is multi louvered at 6.5mm height for airflow, and the fittings are CNC machined aluminum quick connects. There is a race style aluminum drain plug, which anyone who has fought a plastic factory drain will appreciate. Finish is satin aluminum.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eFits 2012 to 2018 N55 cars including the F87 M2, F2X M235i, and F3X 335i and 435i, with and without xDrive. It replaces OEM part 17118672103 and drops straight in using the factory hoses, AC condenser, brackets, and fan shroud, so there is no cutting or modification. Note this fits the original N55 M2 and not the S55 powered M2 Competition.
