SLS/R197/C197 AMG: K&N Fitlers for the SLS AMG!!!
I went and tested out first the BMC filters and the K&N Filters on Android's Software "Torque". The maximum mass air flowrate for the BMC came out to be 425 g/s and for the K&N I got 440 g/s. This means that the K&N filters slightly have a better air flow rate.
Now I know when you go to K&N's website, you will not find air filters available for the SLS.
Just let's find out how I got them

Here are some pics


This is the BMC. Notice that I have removed the oil from the filter. I do that to protect the MAF Sensors from the oil.

And here now I have fitted the K&N Filter.



Before using them I decided to remove the oil from them

Nice and Clean Now


Just to give an idea of how much oil there was

In conclusion I find that the K&N filters allow a better air flowrate than the BMC air filters. In addition the K&N filters are cheaper as well.
For BMC filters the total price come out to be $172.92 through BMC's website. The K&N filters I got them for $82! A little bit more than half.
Notice that on the website you won't find K&N filters that fit for the SLS AMG

Good you won't be driving it on a dusty day

It does not make good sense to remove the oil from the air filters . The oil is there to help remove small dust/dirt particles. Just lay the pre oiled filters out in the sun for a short while ( half hour or so ) and the excess oil with dry off. Again it does not make good sense to use the filters without oil. You are asking for engine damage due to insufficient air filtering. K & N would not pre oil the filters if it was not effective/safe.
For those who want to know which K&N filter fits the SLS, it can be found here
However, for the filter to fit exactly, you will need to trim some of the edges. This can be done using a razor blade for example. The first ones I bought got damaged becuase I forced to close the Airboxes on them while using them.
The new ones I trimmed the edges and now there are no problems.
