ISR Performance T3/T4 Turbo Blanket

The ISR Performance T3/T4 Turbo Blanket is a universal-fit thermal insulation wrap for T3 and T4 flange turbochargers. Reduces under-hood temperatures by trapping heat inside the turbo housing, protecting critical components like brake and clutch master cylinders from radiant heat damage.

What It Does

Turbochargers generate massive amounts of heat that radiates out into the engine bay during operation. Over time, this heat damages nearby components, including brake master cylinders, clutch master cylinders, wiring, plastic intake parts, and rubber hoses. A turbo blanket wraps the hot side of the turbo housing in heat-resistant insulation, keeping that heat contained within the turbo where it actually helps spool efficiency, instead of cooking everything around it.

Fitment

• T3 exhaust housings
• T4 exhaust housings

Critical fitment note: This blanket will NOT fit T25 exhaust housings. Verify your turbo housing size before ordering.
