In this entry, I get my hands on the 3D printed prototypes of the upcoming S85 CSL Competition Complete Carbon Intake System. I provide insights into the target specifications by reviewing the CAD designs and lay down my expectations of the kit.
In a true echo to the V10 M5 ethos, this Build Journal entry has best reflected a 3 months cycle of lows and highs with my E60.
I cover the initial tuning tests, the tuning dilemma of the OE+ variant of the plenum, my AlphaN realization and chat on MAF map compatibility.
We discuss why the S85 was built for AlphaN, the mapping process and I end with my driving impressions drawing a comparaison with its younger brother: the M3 V8.
