SLK55 Dyno Test
Mid length headers
Eurocharged Tune

Tried several different air intakes 3.5 Tube vs Stock at the end of the day it made no difference.... intake manifold temp was the determining factor, we let the car sit for 10 minutes and got the 340hp 353TQ... the lowest... 321 was the result of back to back to back runs

Which air boxes did you try? When I had my C55 (same engine as your SLK55) I saw an improvement on the dyno with the Renntech airbox.

We ran stock vs a 3.5" tube intake w/filter and w/o filter... heat really dictated the result with any of the intakes
