Replace your old and dirty air filter with a Drop-In Air Filter for your 2006-2007 Chevy/GMC 6.6L LLY/LBZ Duramax. The air filter in your vehicle serves as the first line of protection against harmful airborne debris that can damage your engine. Direct-replacement drop-in filters are manufactured with a paper filter media, and aftermarket filters are made with an oiled cotton-gauze, or synthetic dry filter media. Drop-in air filters get their name from their designn as most have a "drop-in" installation and simply fit inside the factory air box. XDP carries drop-in air filters from manufacturers like S&B Filters, AFE, K&N Engineering, so you can find the best one to meet your vehicle's needs.
