Cobb Tuning [15-21 WRX] Turbo Blanket

The COBB Tuning Turbo Blanket for the 2015-2021 Subaru WRX is designed to retain useful exhaust energy at the turbine housing while reducing heat transfer into the engine bay. Its fire-retardant volcanic-rock outer layer is rated to 1500F direct heat and 1800F radiant heat, and calcium-magnesium-silicate insulation is rated to 1800F direct heat and 2300F peak heat. The blanket helps improve turbo response, lower intake temperatures, and protect nearby under-hood components from heat soak.
