4.5-16 Duramax LLY,LBZ,LMM

Specifically designed to fit the 2004.5 to 2016 Duramax LLY, LBZ, LMM and LML VGT Turbochargers. The blanket covers the entire exhaust housing precisely covering all the important areas to reduce heat in the engine bay directly from the turbo by up to 80% and to surrounding components. (Far better than the stock piece of metal they put over the turbo…) Our Lava line of blankets are different from our other turbo blankets in that they feature an outer jacketing that is made from an extremely heavy duty and high quality pulverized lava rock fiber instead of silica impregnated fiber.  This lava material is actually different than what any other turbo blanket manufacturer uses in that it features an aluminum bonded layer on the inside of the blanket to further reflect the small amount of radiant heat which makes it through the ceramic layer.
