These plugs are for the drain which is in the OEM location and the other is removed so the OEM temperature sensor can be installed in its place.
The CSF radiator has a high-mounted vent to make bleeding the cooling system easier. This is the screw plug to the right in this picture.
The plug on the left is the coolant drain plug, the one on the right is removed to install the OEM temperature sensor.
Installation starts by removing the lower panel to access the fan assembly bolts and the coolant temperature sensor plug.
Next, the air box and air filter assembly are removed to access the fan bolts and the upper mount bolts.

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.
