FLOW BENCH RESULTS
Flow rate testing is performed to validate the design against the restrictive stock airbox. Using our in-house Superflow bench, the maximum possible flow rate in CFM (cubic feet per minute) is measured in gains over stock at a variety of test pressures (in/H20). A higher flow reading means the intake system can support increased demands from ECU tunes and turbocharger upgrades.
Repeated flow bench results show the Massive Improvements from our intake system.

DYNO RESULTS
In addition to flow bench testing, real world power numbers are achieved using our in-house dyno cells to see the effect the improved flow rate has on horsepower and torque. The testing was performed in controlled conditions on an IE Stage 1 tuned car performed the same day back to back on multiple octanes.
Dyno results show consistent and significant power gains above 5000RPM where the stock airbox reaches the limits of possible flow to support the power.
POWER SUMMARY
The above gains are a result of various design details:
- The large internal volume, Massive air filter, and multiple air sources allow for an unrestricted supply of airflow.
- The internal velocity stack provides a low-turbulence transition from the filter to the Inlet pipes.
- The carbon fiber airbox both channels ambient temperature air quickly to the turbochargers and protects the airflow from engine bay heat.
