The 2004.5-2005 model year LLY Duramax trucks are quite powerful for their make year. But since 2005, manufacturers have made advancements and improved the air intake systems drastically. Aftermarket manufacturers such as aFe, Banks Power, and AEM have made even greater improvements, allowing the truck to intake much more oxygen. At HeavyWeight Diesel, we stock their highest quality air intakes that will improve your truck's horsepower, torque, and mileage. Your truck will be healthier and you'll be able to make further modifications. HeavyWeight Diesel invites you to look through our exhaust systems and programmers; Pairing them up with an air intake will create an optimal system, and in turn, a powerful Duramax.
The cleaning kits we stock will help out short-term, but our air filters will supply the engine with clean oxygen while filtering contaminating particles. Diesel engines benefit from quality air filters the most, and your Duramax will create better combustions. Contact HeavyWeight Diesel and we will help you choose the best air filter for your LLY Duramax.
