2020-2026 Duramax S&B Cold Air Intake Kit (75-5136)

This kit will come with a fully enclosed airbox that protects the filter from dirt and keeps out engine heat. With an efficiency rating of up to 99.26% at the highest-rated CFM and an airflow improvement of up to 51.83%, you can be sure that you are receiving a quality filter that will increase performance while still protecting your truck! This intake features three air inlet points. If you want to customize the amount of air you take in, S&B provides an optional box plug that can seal off one inlet point.

When to use the Box Plug? 

Stock intake boxes are a significant contributor to poor airflow which is why S&B designs custom air boxes with secondary and/or enlarged openings. With that said, S&B recognizes the benefits of cooler air, so they have included a plug to seal off the opening if desired. For optimal performance, S&B recommends that the intake be used without the box plug, except in conditions of an extreme heatwave.

Available in either 8 layer Cotton Cleanable or Dry Extendable Options

Cleanable is great for people that run their trucks in the city and highways and tend to stay off dusty roads. They last the longest and are cleanable with the S&B Cleaning Kit. If you tend to keep your truck on the pavement, this is the filter for you.

Dry Filters are meant for trucks that typically are used in dusty environments. Extend the life of the filter by blowing it out with compressed air. Dispose of the filter when you're done with it. If you tend to spend most of your time in the bush, working, and cruising logging roads this filter is for you.
