Calibrated air intake tract for internal combustion engines
Abstract:
A Calibrated Air Intake Tract for Internal Combustion Engine is disclosed. The intake includes a Mass Airflow Sensor section that defines an inner diameter that differs from the diameter of the overall intake air tract piping. The Mass Airflow Sensor length and diameter are precision-tuned in order to provide the best engine performance without the typical “check engine” light being lit due to faulty mass airflow sensor readings.
