Our cold air intake 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.
THE SOUND OF PERFORMANCE.
The huge air filter and tube produce a more aggressive sound than stock. Click the play button to listen from outside and inside the cab.
NO MORE CHECK ENGINE LIGHTS.
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 its properly mapped Mass Air Flow Sensor.
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.
MULTIPLE AIR INLETS
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.
