2nd Gen S&B 75-5090 Cold Air Intake UpgradeWith an air box this big, it's no wonder this intake out flows the stock intake system by 40.5% while still maintaining an efficiency rating of 99.81% with a cleanable filter. When running a dry filter our testing showed a 39.3% increase in airflow and an efficiency of 99.68%.
Bigger is better. The OE air opening pales in comparison to the massive inlet we created for this intake. The stock inlet is very restrictive. Our inlet is massive and includes radiused edges to maximize the airflow.
Feed more air to your engine. Our uniquely designed tubing for the 94-02 Cummins intake has flat surfaces through the U-turn section of the tube to decrease restriction of airflow. The lower the restriction, the better the airflow.
Quality Down to the Last Screw. High quality products are an obsession of ours, so you only get the best components when buying S&BCleanable or dry filters. You pick. We offer intakes with two types of filters:
Cotton (cleanable) or Dry (disposable). Since you are not sacrificing performance with either choice, the decision comes down to would you rather throw away the filter or clean it. The part number for intakes with a dry filter end with 'D'.
