Sweet2002 - I hope you are reading all the past threads and knowledge on the effect of higher boost levels and in particular the NW intake manis....thats where you get most increases in torque - across the board - the intake manis specifically add better bottom end response (I guess - possibly becasue they arent tapered like the OEM's)....but I'm not sure the NW manis will fit an SLK32 with possibly less room under the hood...(note: I damaged my stock air filter after a broken angine mount - so she's close already)....
