The all new redesigned intake kit for the 2001-2004.5 LB7 Duramax 6.6L takes advantage of our latest silicone seals and air filter designs. With improved air flow by over 15% than previous model, the simply outperforms the stock intake and looks better too.
With the cotton filter installed, this kit out flows the stock intake by 49.5% while maintaining a 99.81% efficiency rating. When using the dry disposable filter the numbers were equally impressive. Airflow was increased by 47.2% while stopping 99.68% of the dirt. Both filters were tested at 653 CFM.
We designed this kit to avoid check engine lights with a properly mapped Mass Air Sensor. This is where we run away from the competition. Vehicles are becoming more complex. S&B devotes a huge amount of resources to engineer intakes that will allow your engine to run properly with the stock calibration or with enhanced tuning.
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.
