Air Rams

Primarily over-highway trucks
For engine airflow of 700 to 1000+ cfm
Improves intake system airflow and fuel economy by reducing restriction. Examples:

  • at 33 mph, 53 kmh = 3.5″ H20 restriction
  • at 45 – 52mph, 72 – 74 kmh = 4″ H20 restriction
  • at 60 mph, 97 kmh = 5″ H20 restriction
  • Lightweight, non-corrosive, and durable — no service needed
  • Inlet screen prevents large debris from entering intake ducting
  • Side louvers ensure continuous airflow to intake system
  • Common inlet sizes fit most installations
  • Eliminates water from air intake system
  • at 700 cfm airflow = 90%
  • at 800 cfm airflow = 93%
  • at 1000 cfm airflow = 93%*

* based on item H001660

Installation Note
All Air Ram inlet hoods MUST be installed with the screen facing forward to ensure best performance.
Airflow restriction will not be reduced if the Air Ramfaces sideways; but if it faces backwards,
restriction does increase and adversely affects engine performance
