The lower radiator hose is removed to be transferred to the new CSF radiator.
The CSF radiator core is 42mm thick vs the stock core at 28mm thick. The differences are super obvious here.
The CSF radiator has a 5mm fin pitch as we mentioned previously and we measured the OEM fin pitch at 5.3mm. This means that the CSF radiator has more fin area for better heat conduction.
The right side plug is removed so the OEM temperature sensor can be installed.

Would love to know if CSF has any plans to make replacement radiators for the BMW F chassis cars with the B58 engine.
They do and we have tested them here.
y’all plan on testing the Acuity reverse flow radiator hoses?
It is an interesting concept, and if given the opportunity I would like to try it.
How much did this decrease instances of limp mode?
possibly all of it. at least with a stockish motor
Can you share which front mount intercooler you used? I’m running the PRL intercooler and stock radiator on my DE5, and debating if I should swap back to OEM intercooler (less airflow blockage to the radiator I’m told) in conjunction with a beefier radiator.
The car the radiator was tested on was running the stock intercooler. Currently the only cooling mod is the CSF radiator (still on stock coolant too). The CSF radiator alone may take care of your temps and allow you to continue running your aftermarket intercooler. FYI, CSF is also currently developing an oil cooler kit.
Having a ton of experience tracking the FK8 (same drivetrain) you will need a secondary radiator and dual oil coolers if you actually want to push for 15-20 minutes and are setting fast lap times. A radiator alone will not do it.
