COBB TURBO BLANKET FOR VW GTI, GOLF R, GLI, AUDI S3, A3

The COBB Turbo Blanket is designed to insulate the turbine housing of your turbocharger, improving performance and protecting surrounding components from excessive heat. By limiting the amount of heat that radiates into the engine bay, the blanket helps extend the life of underhood parts, reduces intake air temperatures, and improves overall efficiency.

Constructed with a fire-retardant volcanic rock outer layer rated for 1500°F direct heat and 1800°F radiant heat, the COBB Turbo Blanket is built to withstand extreme conditions. Inside, it features high-temperature calcium magnesium silicate wool insulation rated for 1800°F direct heat and 2300°F peak heat. This rugged dual-layer design ensures maximum heat containment while maintaining durability.

Performance benefits are equally impressive. By insulating the turbine housing, the COBB Turbo Blanket prevents useful exhaust energy from dissipating as heat, improving turbo RPM acceleration. This translates to faster spool times and quicker access to peak torque, enhancing throttle response for both street and track driving. It also helps reduce heat soak to neighboring parts of the turbo system, further optimizing reliability and performance.

Designed as a direct fit for the Mk7 Volkswagen GTI and Golf R, the COBB Turbo Blanket also fits GLI, Audi S3, and Audi A3 turbo applications. Easy to install and engineered for long-term use, it’s a smart upgrade for enthusiasts looking to improve turbo efficiency while keeping engine bay heat under control.
