Mishimoto 01-07 Chevy/GMC 6.6L Duramax Degas Tank - Natural

Two decades of heat cycling plastic components, such as your factory degas tank, will undoubtedly make them brittle and discolored. If your factory plastic degas tank is leaking, you're sick of seeing that ugly yellow plastic, or want to go single big turbo and need more space, then look no further. The Mishimoto aluminum degas tank for 2001-2007 Chevy/GMC 6.6L Duramax (LB7/LLY/LBZ) solves all these problems.----Designed with durability, style, and clearance for big turbos in mind. The fully TIG-welded aluminum construction ensures this will be the last time you need to replace your degas tank, and will spruce up your engine bay in the process. We specifically designed this tank to fit with big single turbos without any trimming or worry about melting your tank. The available micro-wrinkle black powder coated finish is perfect for a clean, stealthy look

Mishimoto aluminum degas tanks add some additional reliability and engine bay styling to your vehicle. The stock degas tanks are prone to failure after years of constant temperature variations; while the Mishimoto tanks are constructed from TIG-welded aluminum for optimal durability and longevity. The engineers at Mishimoto have included a 1/8 in. NPT plugged port for an optional pressure sensor. These degas tanks feature a polished or black powdercoat finish that will look great in your engine bay. As with all of the Mishimoto products, these expansion tanks include their lifetime warranty. Order the size and style recommended for your vehicle.
