Get the Direct-Fit Hoses & Clamps products you need for the intercooler system on your 2011-2016 Chevy/GMC 6.6L LML Duramax. Many aftermarket boot kits feature a durable silicone construction for added durability and long term strength. A direct-fit hose and clamp kit generally refers to a replacement component or set that is specially made to fit under your hood just like the factory component it's replacing. The original boots in your intake and intercooler system are typically built with inferior materials that often degrade over time due to oil, heat, and underhood conditions. A ripped or torn boot can cause boost leaks that reduce engine efficiency and rob you of power. AFE, BD-Power, and Mishimoto are just some of the high-quality brands you�ll find.
