Using this intake kit is easy. First, make sure your vehicle is turned off and cool. Then, remove the old intake system from your 2007.5 - 2018 Dodge with a 6.7L Cummins engine. Install the new 4-foot intake kit in its place, using the provided boot and clamps to secure it tightly. Attach the dry air filter and the outerwear's pre-filter cover. When it comes to maintenance, regularly check the air filter. If it looks dirty, clean or replace it. The powder-coated parts are durable, but avoid harsh chemicals when cleaning. Keep in mind that this product is not in stock, and it may take 40 or more business days to arrive after you place an order.
