Turbo Titanium Thermal Blanket T25 T3 T4 T6

Titanium turbo heat blanket: keep the heat where it belongs

This titanium turbo heat blanket made from titanium fiber slips over the turbocharger housing and keeps the heat inside, where it maintains gas velocity. The immediate result: faster response times, a significantly cooler engine bay, and neighboring hoses that last longer. Four sizes cover almost every turbo on the market, from the small T25 to the high-flow T6.

Why choose this turbo heat protection

• All-titanium fiber: the material is made from pulverized and spun volcanic rock, not simple coated glass felt.
• Up to 1204°C at peak depending on the size: 815°C for the T25, 1093°C for the T3, 1149°C for the T4, and 1204°C for the T6.
• Faster response times: by retaining thermal energy on the turbine side, the wheel reaches higher RPMs sooner, reducing low-end lag.
• Mounting hooks and 2 locking springs included: the blanket stretches over the housing and stays firmly in place, even under vibration.
• Carbon fiber look: a dark, woven finish that looks great in a well-kept engine bay.
• Four colors: titanium, red, blue, and black, to match the rest of your build.

Turbo heat shield: what it changes under the hood

A turbo heat shield is an insulating wrap that surrounds the hot section of the turbocharger. It serves a dual purpose. On the inside, it maintains exhaust gas temperature: hotter gases move faster, making them more effective at driving the turbine. On the outside, it lowers the ambient temperature of the engine bay, protecting nearby hoses, wiring harnesses, and intake air. It is one of the few modifications that improves engine response without touching the ECU map, and it takes an hour.

Which size to choose

The size is indicated on your turbo's flange, not the vehicle. The T25 fits T2, T25, T28, GT25, and GT28 turbos. The T3 is designed for T30, T32, and T35. The T4 fits T4, GT40, GT42, and GT45. The T6 is for large setups like the T5, T6, GT55, HX52, HT60, and T888. Check compatibility by model before installation: measure the circumference of your housing if in doubt.

Installation and maintenance

Allow 30 minutes to 1 hour with a cold engine. Position the blanket around the turbine-side housing, thread the hooks through the eyelets, and tighten with the two springs until the material fits the shape without wrinkles. Never wrap the center housing or oil inlets: only the exhaust section should be covered. During the first few starts, a little smoke and a cooking smell are normal while the binders evaporate. Maintenance: check the tension of the springs at every oil change and brush dry, without solvents.

Frequently asked questions

Is a turbo heat blanket really useful?
Yes, in two measurable ways: the temperature under the hood drops significantly, and boost builds sooner because the gases retain their energy until they reach the turbine.

How do I know if my turbo is a T3 or a T4?
The designation is on the turbine-side outlet flange and in the turbo's part number. Otherwise, measure the housing circumference and compare it to the stated 48 cm.

Can the blanket damage the turbo?
No, as long as it stays on the exhaust section. The center housing and oil lines must remain clear to dissipate their own heat.

Does it smoke on the first heat cycle?
Yes, slightly, for a few minutes. The surface treatment is curing; the phenomenon will then disappear permanently.

Do I need to remove it for an emissions test?
No, it is a heat shield, not an exhaust system modification.
