Fits: 2004.5 thru 2005 Chevy Silverado/GMC Sierra 2500HD/3500HD LLY Duramax Diesel

S&B's cold air intake for the 2004.5-2005 Chevy / GMC Duramax LLY 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.

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.
• This intake pairs VERY well with S&B's Turbo Inlet Pipe. 
• 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.
