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.
PROTECT YOUR ENGINE
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.
NO MORE CHECK ENGINE LIGHTS
S&B devotes a huge amount of resources to engineer their intakes to allow your engine to run properly with stock calibration or enhanced tuning. This kit was designed to avoid check engine lights with its properly mapped Mass Air Flow Sensor.
SILICONE INTEGRATED SCOOP
On the L5P intake kit, S&B has an integrated silicone air scoop that feeds even more air to the filter.
MULTIPLE AIR INLETS
More air 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, S&B includes an optional box plug that can seal off one inlet point.
