PSR Volcanic Rock Turbo Heat Blanket - T25 Turbine HousingsConstructed from pulverized volcanic rock that is refined into high temperature fiber, the PSR Turbocharger Turbine Housing Heat Blanket is engineered to deliver superior thermal protection in extreme conditions. This advanced material can withstand direct contact temperatures up to 800C and radiant heat up to 1200C, helping to retain more energy within the turbine while dramatically reducing under hood heat. The result is lower intake air
