Using this intake kit is a breeze. First, gather your basic hand tools. Then, remove the restrictive factory intake from your 2001 - 2004 GM vehicle with the LB7 6.6L Duramax engine. Install the new intake pipe, air box with lid, dry air filter, and the outerwear's pre - filter cover. Use the included installation hardware, silicone boot, and stainless - steel T - bolt clamps for a secure fit. Remember, this product isn't in stock, and you'll have to wait 10 - 15+ business days on average to get it. For maintenance, regularly check the dry air filter and clean or replace it as needed. Keep an eye on the clamps to make sure they're tight. That way, your engine will keep getting the best performance from this intake kit.
