S&B's cold air intake for the 2017-2019 Silverado / Sierra Duramax 6.6L was engineered to minimize air restriction and flows 47.70% better than stock. This kit comes with a fully enclosed airbox that protects the filter from dirt and keeps out engine heat. Inside you'll find 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. S&B devotes a huge amount of resources to engineer their intakes allowing your engine to run properly with stock calibration or enhanced tuning. This kit was designed to avoid check engine lights with it's properly mapped Mass Air Flow Sensor. On the L5P intake kit, we have an integrated silicone air scoop that feeds even more air to the filter resulting in more air and better performance. The L5P intake kit features two large air inlet points. If you want to customize the amount of air you take in, we include an optional box plug that can seal off one inlet point.

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.
