Are you ready to up your airflow in your 3.0L GM 1500 Duramax for improved performance and fuel economy with the highest quality cold air intake on the market? If so, you found it!

S&B builds cold air intakes, and that's all that they make, so they're pretty darned good at it. With S&B, you'll find that they only use the highest quality materials coupled with the best machinery built in the USA and do it all at a price point that's pretty tough to beat.

MAXIMUM PERFORMANCE: The cold air intake for the Silverado / Sierra Duramax LM2 3.0L 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.

NEW SNAP IN LID DESIGN: The new snap-In lid design requires no screws to secure it to the box. This makes installation and inspection quick and easy. Our silicone edge trim ensures an airtight seal, protecting against unwanted, power-robbing engine heat.

PREMIUM SILICONE COMPONENTS: The air filter, coupler, lid seal and box plug are all made with silicone. Silicone is a premium rubber that will seal better and last longer. It handles temperatures as high as 400F without cracking or tearing and won't deteriorate over time.

CHOOSE YOUR AIRFLOW: More air equals better performance. The Duramax LM2 3.0L intake features three air inlet points. If you want to customize the amount of air you take in, we provide an optional box plug that can seal off one inlet point. When to use the Box Plug? Stock intake boxes are a significant contributor to poor airflow which is why S&B designs custom air boxes with secondary and/or enlarged openings. With that said, S&B recognizes the benefits of cooler air, so we have included a plug to seal off the opening if desired. For optimal performance, we recommend that the intake be used without the box plug, except in conditions of an extreme heatwave.

NO 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 it's properly mapped Mass Air Flow Sensor.

Wow!
Color: Farmhouse White, Number of Items: 2
This comes as a two pack and I was thinking it might be cheap looking or be made of inferior materials. These end tables are solid and beautiful when put together. They come unassembled but the instructions are very clear and understandable. Highly recommend this product. Well worth the price.

Well engineered!
Color: Farmhouse White, Number of Items: 2
These are really quit easy to assemble. They're well engineered. One or two extra screws/parts in case you loose one. When they're done, they look Very Nice! I have tremors and was still able to put them together, it took alittle longer that an hour, but still not difficult.
