S&B's cold air intake for the 2001-2004 Chevy / GMC Duramax LB7 6.6L was engineered to minimize air restriction and flows 43.69% better than stock. This kit comes with a fully enclosed airbox that protects the filter from dirt and keeps out engine heat. This kit comes with a massive, highly-efficient air filter which results in better performance and protects your engine. Available in either 8-layer Cotton Cleanable or Dry Extendable media. 

Optional add-ons include an extra filter (Dry or Oiled) and a cleaning kit. Having an extra filter on hand means you can replace the filter when needed then either purchase a new dry, disposable one or clean the reusable filter when it is convenient. S&B's service kit will come with enough cleaner and oil to service a cotton re-usable filter approximately 3 times.

  • Removable, clear polycarbonate lid for a great finished look
  • New lid seal protects the edges and secures it to the air box
  • Injection molded MAF plate ensures true o-ring seal to the sensor
  • Fit and finish are second to none
  • Installs in less than an hour and outperforms the stock intake


  • S&B Cold Air Intake System
  • Installation Hardware


DmaxStore Note:

  • Adding an extra filter and/or cleaning kit saves time, and money on shipping.  
  • Air Box Plug: Removing the plug will allow for maximum flow, however, water and debris are more likely to make it into the box. If your truck is constantly driven in a dirty environment, consider leaving the plug installed.
  • Consider adding a S&B Filter Wrap to extend the life of your filter by shielding it from large debris like leaves, sticks, and bugs that can find their way into your air box and eventually damage the filter.

Awesome product quick delivery. Very fast, straight forward install. The clear cover is a great place to put all you E.O. # stickers for the smog guy. Will continue to do business with DMAX Store and S&B filters.


Installed on my LML. Easy to install with step by step direction. Looks great and helps keep the truck running cool, adds a few horses. Great product! Highly recommended
Thanks dmax store


Well Justin my new S&B for my LLY and it’s pretty legit. Looks and feels extremely nice. Not sure if any gains yet but I will report once I do. Definitely quality material and extremely easy to install did it in the blistering cold pitch black outside and windy took about 40 minutes total. Not bad can’t wait to get the S&B turbo mouthpiece next then the two together will the power come. Thanks DMax

Awesome intake, went with the dry filter option with a filter wrap for a little extra protection. Install was easy, fast, and simple. Performs great and look good too! Can\'t go wrong with option for your Duramax from the Dmax Store!
