The LBZ 2006-2007 Duramax produces great power on stock parts, but what would take it to the next level is an aftermarket air intake that would allow the truck to breathe easier. A less restrictive air intake would supply the Duramax engine with more oxygen, resulting in better internal combustion. You would notice an improvement in horsepower, torque, and mileage, and you would be able to modify your truck further adequately. Here at HeavyWeight Diesel, we stock air intakes from aFe, AEM, Banks Power, and S&B. These air intakes are a lot less restrictive, and if you wish to create an even more efficient system, we recommend combining an air intake with exhaust, and a tuner.
At HeavyWeight Diesel, we also stock cleaning kits and air filters. A quality air filter would only let the oxygen through to the engine, by filtering the contaminants and debris. You won't have to worry about oil contamination, and your engine will be healthier due to the cleaner air. The decision on which air filter you should buy depends on your environment, and if you're uncertain, we invite you to contact our HeavyWeight Diesel technicians.
