Get the Direct-Fit Hoses & Clamps products you need for the intercooler system on your 2017-2019 Chevy/GMC 6.6L L5P Duramax. Many aftermarket kits feature a durable silicone construction to provide you with added durability and a long service life. The direct-fit hose and clamp kits are specially made to fit under the hood of your truck and fit in place of the factory components they are replacing. The factory boots in your intercooler and intake system are often made of inferior materials that degrade over time due to heat, oil, and other underhood conditions. A torn boot or failed clamp can cause boost leaks that can rob you of power. You�ll find high-quality manufacturers like AFE, BD-Power, and Mishimoto.
