Using this intake horn is easy. First, locate the old OEM intake horn on your 2017 GM truck with L5P 6.6L Duramax and Factory Style Turbo. Remove the old one carefully. Then, take the new Wehrli intake horn and bolt it in place. Since it's a bolt - on part, you don't need to do any tuning. When using the product, make sure all the bolts are tightened properly to avoid any air leaks. For maintenance, regularly check the intake horn for any signs of damage or debris. If there's dirt, you can use a mild cleaner to gently clean it. Keep it dry before reinstalling. This intake horn is designed to work well with OEM or aftermarket intake kits, so you don't have to worry about compatibility issues when using it on your stock truck.
