consists:
"Specific to each Mercedes-Benz model, the KLEEMANN Engine Performance Kit contains a custom-made pulley set, high airflow filters and a K-Box. The pulley is CNC machined and the diameter is increased and precision balanced to ensure a long service life and full vibration dampening. A new belt idler and serpentine belt is also fitted to maintain OE specifications for belt tension and high-flow air filters reduce pressure drops inside the air box to maximize airflow."

now im not sure i like the sound/looks of the K-box seems like a $1 ebay resistor type device that fools certain sensors. and the airfilters are pretty pointless looking as stock airbox have $millions spent on them, the only thing id do is the SL55 intake y-pipe and perhaps a trusted filter like green or itg at a push.
so has anyone experienced Kleeman pulleys and what are these gains like.
also is it normal to receive a box like K-Box ??? i would have thought a.) send standard ecu off to get professionally flashed to accomodate pulleys and b.) best results RR`s custom remap with new pulleys fitted.
sorry for so many questions just trying to get my head around stuff
