S&B’s new 75-5080 Cold Air Intake kit is an excellent addition to your 2006 or 2007 Duramax if you really want a robust performance enhancer with good looks. This intake has a sleek design and improves airflow by roughly 15 percent over the previous intake kit, significantly outperforming the stock intake. The kit is designed for maximized airflow, as a removable silicone box plug allows for an even wider air swath. The silicone won’t crack or tear as it ages and can withstand temperatures as high as 400°F. A clear removable lid showing the air filter inside includes a rubber seal, giving the intake an excellent finish. A new injection-molded bracket for the MAF sensor has also been installed with a powerful o-ring seal to prevent false illumination of the check engine light. This intake includes a cotton filter. Installation is easy and takes less than one hour. For more information, call 909-947-0015 or visit www.sbfilters.com.
