Open Air 4" Intake Tube W/S&B Filter (2011-2016 6.6L Duramax LML)

We’ve tested sealed box intakes vs open air intakes, and have found that overall vehicles do best without a sealed box around the intake. So we came out with our own 4” Open Air intake kit. These kits use American made parts, w/stainless steel tubing & high quality 7-layer filters from S&B. Let your truck breathe better than the factory intake, while keeping even more dirt out. Our kits come in a raw finish. The raw finish gives you the option to powder-coat it any color you want.
