Hello All,
I currently drive a 2016 340 xdrive, equipped with Dinan; intake, exhaust, mid-pipe, tune, and springs. I am looking to have the car run cooler. After doing some research the solution here seems to lie within the heat exchanger. Therefore I am looking to upgrade to one of the following; https://studiorsr.com/products/csf-b...-charge-cooler Or https://www.ecstuning.com/b-wagner-t...SABEgLAy_D_BwE I am currently following @tyler.genter 's amazing build in which he installed a CSF, but any other advice on the better option here, would be greatly appreciated. Thanks! |

I'm not sure if you're planning on tuning your car, but MHD has this option and I'm running the performance cooling setting and it actually works. I think those bigger heat exchangers will benefit more for higher horsepower applications
- Another nice feature for N55, B58 and N13 cars: We found a way to bring the M switchable coolant feature to non-M cars. With the coolant flash option activated, the coolant target will be 95c in eco / comfort instead of 106c+. If you switch to sport mode (or comfort + transmission in S or M), the coolant target will be 85c with performance or 80c with track option selected. This allows the engine to run cooler and oil temperature will also benefit from that significantly. We also changed many fan settings to further improve how quick the system reacts to the different modes, this also helps to reduce the IAT and under hood temps when staging at a drag strip or slow city driving. |

Interesting note I made while on a back-roads adventure this weekend.. My car typically brings the coolant to ~225-230F (106C as noted), but when I started driving hard, the coolant temp actually came down to just about 200F/95C. That MHD feature seems very useful, since the car (particularly with track handling package's extra radiator) has a lot of cooling ability stock.
More on-topic.. I believe both of the items you linked replace the 'secondary loop''s front radiator? Not the main coolant radiator? So this would help with heat-soak of the Air/water charge air cooler, and handle the heat the AC pumps into the same loop? Personally I see really good intake air temps, but I don't have the mods you do. As for the 'car running cooler' - are you actually getting coolant temps above the targets I mentioned above? If not, the radiator won't help much because the car adjusts the water pump to hit a target temp. If you aren't going above that temp, a 'better' radiator isn't going to change that. |

Thanks for the kind words!
Will definitely provided my feedback when it get's to that point of the build

Several are quick to want to upgrade their engine cooling, yet haven't even proved that the oem system is over-capacity. The fact that it can hit its target temps easily means that there is nothing to upgrade. |

I'm curious, since our ac depends on this same heat exchanger, did anyone notice their ac getting colder after doing this mod? Would be very interesting.

I think there is a bit of a mixup. The B58 has one cooler for the engine cooling, where the cooling management device will always keep the engine temp at the same level. The AC runs independently through its compressor.
The radiators promoted here, are meant to keep the airintake temperatures down so the engine is fed more oxigen for "more power". No impact on the AC either
