Hi, Michael, and welcome to the forum and the world of MB.
MB really engineers their intakes pretty highly. If you check you'll find it is already a cold-air intake. There are some aftermarket things available, but they actually result in drawing in more air from the engine compartment and add noise, but not power.
Take care and enjoy the ride,
Greg
