Helps Reduce Wastegate Heat Transfer
An external wastegate operates directly in a high-temperature exhaust environment. Without adequate heat management, that heat can radiate toward nearby wiring, vacuum lines, hoses, and other components.
The blanket creates a thermal barrier around the wastegate to help reduce heat transfer into the surrounding engine bay.
It is also designed to help reduce heat soak between the wastegate’s main body and actuator area, potentially helping maintain more consistent operating conditions.
High-Temperature Basalt/Titanium Construction
The blanket uses a basalt/titanium heat-resistant material intended for extreme turbocharger exhaust temperatures.
According to the supplied specifications, the material is rated for:
- Up to 1,800°F direct heat
- Up to 2,500°F intermittent heat
These ratings describe the material’s stated temperature resistance and should not be interpreted as a guarantee of a particular underhood temperature reduction.
Helps Protect Nearby Components
External wastegates can generate significant radiant heat, particularly on high-output turbocharged engines.
Adding a dedicated wastegate blanket can help limit the amount of heat radiating toward nearby:
- Wiring
- Vacuum hoses
- Silicone hoses
- Sensors
- Engine-bay components
- Other heat-sensitive parts
Proper exhaust and turbo heat management remains important even when using a wastegate blanket.
Stainless Steel Retention Hardware
The blanket includes stainless-steel hardware designed to secure it around the external wastegate.
Each package includes:
- 1 × 44mm External Wastegate Turbo Blanket
- 1 × Stainless Steel Spring
- Stainless Steel Wire
Wastegate is not included.

Installation
Installation is designed to be straightforward, but the wastegate should be completely cool before beginning.
- Allow the turbocharger and external wastegate to cool completely.
- Position the blanket over the compatible wastegate body.
- Ensure the blanket does not interfere with the actuator, valve mechanism, vacuum/pressure port, or exhaust connections.
- Secure the blanket using the supplied stainless-steel spring and wire.
- Check clearance around wiring, hoses, and other components.
- Confirm that nothing contacts moving or excessively hot components before operating the vehicle.
Do not install the blanket where it interferes with wastegate operation or creates unsafe contact with surrounding components.
Why Use an External Wastegate Blanket?
A wastegate blanket is primarily a heat-management component. By containing some of the radiant heat generated by the external wastegate, it can help reduce the amount of thermal energy reaching nearby engine-bay components.
For turbo builds with tight packaging around the exhaust manifold and wastegate, additional heat protection can be especially useful.
It can also complement other turbo-system heat-management products such as turbo blankets, exhaust wrap, and heat shields.
Frequently Asked Questions
What size wastegate does this blanket fit?
This listing is designed for 44–45mm external wastegates.
Does the 44mm size refer to the wastegate?
Yes. The supplied product information identifies the 44mm version as fitting 44–45mm wastegates. Always compare the physical dimensions and design of your wastegate before ordering.
What is the blanket made from?
The supplied specifications identify the material as basalt/titanium and rate it for up to 1,800°F direct heat and 2,500°F intermittent heat.
Does the blanket include a wastegate?
No. The wastegate is not included. The package contains the blanket and stainless-steel retention hardware.
What comes in the package?
You receive one 44mm external wastegate blanket, one stainless-steel spring, and stainless-steel wire.
Will this fit a GFB EX44?
The blanket is listed for 44–45mm external wastegates, so the GFB EX44’s 44mm valve size falls within the stated application range. However, valve diameter alone does not guarantee that the blanket’s physical shape and mounting arrangement will match the wastegate. Compare dimensions before ordering.
Are other sizes available?
The supplied product information lists 38mm, 44mm, 50mm, and 60mm versions.
Keep External Wastegate Heat Under Control
The 44mm External Wastegate Turbo Blanket provides a compact way to manage radiant heat around a turbocharged exhaust system. Its basalt/titanium construction, stainless-steel retention hardware, and 44–45mm wastegate application make it a practical addition to compatible turbo builds.
If your external wastegate sits close to wiring, hoses, or other heat-sensitive components, adding a dedicated heat blanket can provide another layer of thermal protection.
