S&B's cold air intake for the 2007-2010 Chevrolet 6.6L Duramax LMM was engineered to minimize air restriction and flow 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.
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.
More air equals better performance. The Duramax LMM 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.
The large diameter intake tube was designed to minimize restriction. The tube is positioned in one clean line with minimum obstructions from the throttle body to the air box. This means more cool air and better performance.
