S&B Filters offers drivers one of the best Cold Air Intake Kits on the market for the GM Duramax 6.5L 1992-2000 Diesel trucks. This Stage 2 Intake System is made of plastic instead of metal to help reduce down on the absorption of heat from the engine to keep the air flow as cool as possible, plastic also allow for S&B to sell the intakes at a much cheaper price due to the prices of metal raising over the last few year. All kits are designed as a completely sealed box that only draws air from the factory air inlets to make sure that no hot air enters from the heat coming off the engine to maximize performance gains.
The number one selling feature of the S&B Cold Air Intake however is the filter itself, S&B makes all filters in house from a cotton gauze that can be reused by performing a simple cleaning and re-oiling every time you change your oil or as needed. These cone shaped filters improve airflow over the factory system by increasing the surface area that are can be pulled from and by the material itself allowing a higher volume of are through as well. Don’t let this worry you though the design of the filter is tested to insure that 99% of all dirt that enters the intake does not enter engine by overlapping the layers of the filter to stop all unwanted material.
Some drivers would prefer to not have to clean and oil the filter every time so to meet the demands of this market S&B Filters also offers a Dry Filter that can have the dirt removed by shaking out the filter. This is perfect if you are only driving on highways and don’t always need the higher filtration of an oil filter even though the difference is less than 1%.
