Everyone wants an air intake that will flow more air into the engine to increase horsepower or improve fuel economy. One of our competitors boasted a huge intake tube however, the inside of the tube told a different story. We knew we had to respond. The Mass Airflow (MAF) sensor in the intake tube sends the engine a mass airflow reading that only works when the sensor is in a tube that has a specific cross-sectional area. In other words, if you install a large diameter tube without addressing the MAF sensor, the readings will be so far out of spec that it will result in a check engine light. Our competitor's solution was to eliminate all of the airflow gains they would have achieved from their big tube. They used an insert that restricts the mass airflow to stock performance in order to avoid a check engine light.
For our Ram-Air intake system, we wanted a huge free-flowing tube and no check engine lights. How did we manage it? Our patented electronic Air Mass Control Module recalibrates the stock sensor's MAF readings to accurately report the mass flow to the truck's ECM. This allowed to increase the tube size without limits.
The Air Mass Control Module is available with our 2020-2023 Duramax L5P Ram-Air Intake System [ Ссылка ]
