The 2004.5-2007 5.9L Dodge Cummins has an efficient air intake system from the factory, however, manufacturers have made improvements to the air intake systems, and if you wish to make incredible power, an aftermarket air intake is a perfect start. At HeavyWeight Diesel, we stock air intakes from aFe, Banks Power, and S&B, that will supply your Cummins engine with adequate oxygen. Your truck will improve across the board, and you will notice horsepower, torque, and mileage gains.
Next to air intakes, we also stock cleaning kits and filters for your 5.9 Cummins. The air filters will clear the air of impurities before it enters your engine, improving its health and longevity. You should purchase an air filter based on your condition; If you use your truck for work or off-roading, an oiled, closed air filter will be a better option. However, if you drive your truck on pavement only, an open air filter will allow you to squeeze the most power from your truck. If you're undecided on which air intake or filter to purchase, contact our Heavyweight Diesel technicians for help!
