With the 2025 model year Duramax engines, GM added a new sensor into the intake system to monitor Crank Case Ventilation Pressure. To get past this airflow limitation, we engineered a new patented Air Mass Control Module and a Crankcase Ventilation Control Module that allow the intake to go beyond these limitations for truly unmatched airflow performance. The Banks Ram-Air intake system for the 2025-26 Duramax 6.6L helps the engine produce horsepower at lower RPM, sharpens turbo response, and improves fuel economy by improving air mass flow to the turbo. This is made possible by our patented electronics. Meanwhile, all competitors must retain near stock airflow or risk setting a check engine light.

• Only intake that improves mass air flow over stock
  
• Improves turbo response
  
• Improves fuel economy
  
• Massive filter extends service life, fewer cleanings
  
• Housing keeps out hot air
  
• Housing increases air volume around filter
  
• Connects to OEM hood scoop
  
• Rubber elbow allow for engine movement
  
• Increased turbo sound, no drone
  
• Oiled or dry high efficiency filter
  
• No check engine light
  
• Includes Banks Air Mass Control Module
  
• Includes Banks Crankcase Ventilation Control Module
  
• U.S. Patent 11,193,441

Late-model 2025+ Duramax trucks feature ultra-stringent ECM oversight of crankcase pressure, ventilation flow, and blow-by gases via integrated sensors in the CCV system. Any non-stock alteration—like rerouting for better oil separation, increased ventilation capacity to handle higher boost/performance, or integration with high-flow intakes—risks the ECM detecting "out-of-range" pressure or flow deviations. These deviations result in a check engine light to protect emissions compliance.
