2004-2005 Chevy / GMC Duramax LLY 6.6L S&B Cold Air Intake
Separate the good from the bad with S&B Filters cotton filter cold air intake kits. Lots of cool, clean air has been shown to increase horsepower—and S&B units deliver unrestricted flow and high filtration. Your rig will not only gain performance, but also a sporty high-tech appearance under the hood. The 8-layer oiled cotton filters protect your engine from harmful dirt and debris, and they're cleanable for reuse. In addition, the filters and couplers are designed from silicone, not urethane. This helps ensure they won't degrade or crack over time; plus, they can resist temperatures as high as 400 degrees F. These intake kits are simple to install, and the great looking signature clear lid allows visual inspection of your filter at all times. Remember, there are good air intakes … and then there are the better intakes—demand the better; choose the efficiency and style of S&B Filters cold air intake kits.
