Wehrli pairs a large fabricated aluminum plenum with precision CNC-machined, tapered individual runners. The goal is much more airflow and a more even split between all six cylinders than the cast factory intake shelf gives.
It is meant for extreme drag and pulling engines with extensive head work, where high-rpm power and volumetric efficiency matter most.
