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.

Fantastic Product
I bought these hangers to mount my speakers. They are heavy duty, has a curl at the end to keep the speakers from falling off, and I was able to mount them and have clearance underneath. Awesome!!

Does it's purpose with style
We used these in our pantry and dining room for shelves and they turned out well. The only reason they are hard to install is because of the design (which is very nice) so it is worth it. It just takes time when you you are hanging the shelves, to do it correctly. While they can hold a lot, we realized that a bunch of cans or jars cannot go on these shelves. Luckily we had another option for heavy items (Example: We had about 40ish pounds of cans/jars on a 1x12 board that is 33 inches long with 2 of these brackets...and it was too much). If you do not need to hold a lot of weight, these shelves are a for sure, for the price and quality. If you NEED they for something heavy, then you probably will have to go with something more practical from a hardware store. We LOVE them for our pantry!

Worked as intended
Hubby used these to mount a shelf above a long span of windows. They worked great and allowed a clean visual appearance.

Nice brackets
These are nice sturdy brackets for butcher block shelf however they do bend a bit. We installed in a corner so was able to pin to side wall no problems on big shelf. The smaller shelf about 18” moves a bit up and down when loading. Now very little and no worries about it but not rock solid
