The best PTP turbo blanket for most turbo Subaru owners is the PTP blanket made for Subaru models, while builders running an aftermarket turbo should look at the universal T3/T4 fitment in this collection. Both styles come in colors including Lava, Blue, Red, Black, and Silver,
A turbo blanket wraps the hot turbine housing to help contain exhaust heat at the turbo instead of radiating it across the engine bay. Keeping heat away from nearby hoses, wiring, and intake components is the main reason owners add one. Browse the wider turbos and superchargers and cooling ranges alongside this collection, and check your year and model and your turbo size before ordering.
About the brands
PTP Turbo Blankets is the sole brand in this collection, and its range here is focused entirely on turbo heat blankets. The Subaru-specific blankets are listed in Blue, Black, Red, and Lava, for Subaru turbo owners. The universal T3/T4 blankets come in Blue, Lava, Silver, and Red for cars running a T3/T4-frame turbo. Choosing between the two is a fitment decision first: Subaru housing or T3/T4 housing, then color.
Turbosmart is the boost-control name many of these owners already run alongside a blanket, known for blow-off valves, wastegates, and boost controllers for turbo cars. A blanket manages heat at the housing, while Turbosmart parts manage boost pressure, so the two upgrades address different parts of the same turbo system.
Forced Performance Turbos and Blouch Turbos are the turbocharger brands shoppers compare when the turbo itself is being upgraded. If you change turbo frame, confirm the new housing size first, because the Subaru and T3/T4 versions are not interchangeable by assumption.
GrimmSpeed is known for Subaru-focused bolt-ons, including exhaust and engine-bay parts that live close to the turbo. Owners building a complete, heat-aware engine bay often pair a PTP blanket with GrimmSpeed hardware and the wider intercoolers range. For background, read a guide to Subaru engine modifications.
Frequently asked questions
Should I buy the Subaru blanket or the universal T3/T4 blanket?
Buy the version that matches your turbo housing. The Subaru blankets are listed for Subaru models, while the universal version is listed for T3/T4 turbos. If your turbo has been swapped, check the housing frame rather than going by the car alone.
What does a turbo blanket actually do?
It insulates the turbine housing, helping keep exhaust heat contained at the turbo and reducing the heat radiated into the surrounding engine bay. It is a heat-management part, not a power adder on its own.
Is a turbo blanket hard to install?
Fitment is usually a wrap-and-secure job around the turbine housing, but access on a Subaru engine bay can be tight and the turbo must be cool before you start. If the turbo is being removed for other work, that is often the easiest time to fit one.
Does color change how the blanket performs?
The listings separate the Subaru and T3/T4 fitments and then offer color choices such as Lava, Blue, Red, Black, and Silver. Choose fitment first, then pick the color that suits your engine bay.
