2006-2007 GM 2500HD/3500HD 6.6L LBZ Duramax Intercooler Pipes & Intake Accessories

If you're thinking about upgrading the factory intercooler equipped on your 2006-2007 GM 6.6L Duramax LBZ, it's best to replace the tubing associated with the intercooler while you already have your truck torn apart. Here at Alligator Performance, we carry a ton of Intercooler Tubing upgrades that promote improved engine efficiency and increased horsepower during any high-performance applications. While new tubing won't directly affect the power gains that come with an aftermarket intercooler, it will help keep your engine under control while allowing for faster heat dissipation each time you get behind the wheel. Pair these new tubing components with an aftermarket Cold Air Intake or some premium Turbo Upgrades to unlock the full potential out of your Sierra/Silverado.
