2006-2007 GM Duramax 6.6L LBZ Cold Air Intakes
The factory intake on your 2006-2007 GM 6.6L Duramax LBZ is certainly not the most efficient system, leaving a lot to be desired when it comes to engine potential and performance. An aftermarket cold air intake is the best way to deliver an increase in both power and performance to your 6.6L Duramax engine. The right cold air intake system provides large volumes of cold, clean air to your diesel engine which results in improved power, performance, and throttle response for every situation. Most of these aftermarket intakes kits come standard with larger air filters that better protects your 6.6L Duramax engine from contaminants, promoting long-lasting engine and component life without compromise. All of these GM 2500/3500 intake systems are super easy to install, letting you add some drop-in power in a hassle-free package. GM Duramax Fitments: 2006, 2007 GM 6.6L Duramax.
