The Cobb Stock Turbo Blanket fits the factory turbocharger on 2015-2021 Subaru WRX models with the 2.0L FA20F engine. This heat shield wraps the turbo housing to contain exhaust heat, lowering air intake temperatures and shielding engine bay parts from radiant heat. Drivers see consistent turbo response and reduced heat soak during spirited driving or track use.
