Description

The stock setup is limited to a maximum flow of 400 CFM at 28” H2O, whereas our full intake system achieves a significant 31% improvement, flowing 525 CFM under the same conditions.This increase in airflow is paired with a dramatic reduction in pressure drop across the system, allowing the turbocharger to spool faster and operate in a more efficient range of its compressor map.
