This listing is for a clean OEM 2004-05 Chevrolet/GMC 6.6L Duramax Diesel, LLY Engine air cleaner assembly. It was removed and replaced with an aftermarket system for improved performance only. This truck had very low mileage compared to what you typically find. It makes a great inexpensive repair part for a cracked damaged or saturated box. These parts sell new for over $600 making this assembly a real deal! It was carefully removed and will be properly packaged to ensure safe delivery right to your door. Don't miss out on genuine OEM quality at this low price! Thanks for looking.
