Universal Internally Wastegated GT25 GT28 Turbo Blanket – Black

The Thermal Zero GT25 GT28 Turbo Blanket is engineered specifically for internally wastegated GT25 and GT28 turbochargers, making it a perfect fit for a wide range of OEM and aftermarket turbo applications. Whether you’re building a street car or a track-focused setup, this turbo blanket is designed to control heat where it matters most. At the core of the blanket is 1-inch-thick, 6 lb density ceramic insulation, capable of withstanding over 2500°F of direct heat. This insulation is protected by a high-temperature silicone-coated outer shell, available in Black, Red, Blue, Chrome, or Gray, for both durability and style. Unlike standard turbo blankets, Thermal Zero blankets feature a knitted stainless steel wire mesh inner layer. This mesh separates the insulation from the turbocharger housing, significantly reducing vibration-related wear and preventing material breakdown over time — a common failure point in lower-quality turbo blankets. By installing a Thermal Zero turbo blanket, you can reduce radiant turbo heat by up to 80%, helping to: Improve turbocharger efficiency Promote faster spool Lower under-hood temperatures Protect nearby components from heat soak If you’re unsure whether this turbo blanket will fit your setup, review the known compatible turbocharger models below, or measure your turbocharger and compare it to the sizing diagram above to confirm proper fitment.
