S&B's cold air intake for the 2017-2019 Silverado / Sierra Duramax 6.6L was engineered to minimize air restriction and flows 43.86% better than stock. This kit comes with a fully enclosed airbox that protects the filter from dirt and keeps out engine heat.
Important Note: The previous version of this intake kit (part numbers 75-5103) has been discontinued.
This kit comes with a massive cleanable cotton highly-efficient air filter which results in better performance and protects your engine. For the Dry Extendable Filter Kit, See 75-5103D.
S&B devotes a huge amount of resources to engineer our intakes that allow 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.
S&B's signature clear lid is integrated right into the silicone air scoop that feeds more air to the filter, and provides great looks. 
Multiple air inlets for more air, which equals 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 optonal box plug that can seal off one inlet point.
