How do I determine what size turbo blanket I need for my turbocharger? August 18, 2016

Your turbo blanket selection should be based on the outer diameter of the casing of your turbocharger's "hot side" (which houses the exhaust-fed impeller). Therefore, you should either look up or manually measure the diameter of your turbocharger's hot side, as described in the above figure, and purchase the appropriately-sized turbo blanket. Our PTP universal turbo blankets are tailored to fit perfectly turbochargers with external wastegates without any modification. If your turbocharger has an internal wastegate, however, you may need to make a simple modification to allow it to fit appropriately. (e.g., cut away a portion of the turbo blanket)

Please use the following table to determine the appropriate size for your turbo blanket:

Hot Side Diameter Universal Turbo Blanket Sizes:
5 to 6 inches T3 turbo blanket
6 to 7.5 inches T3/T4 turbo blanket
7.5 to 8.5 inches Large T4 turbo blanket
8.5 to 10.5 inches T6 turbo blanket

Please note that we also offer turbo blankets that are custom designed to fit Subaru WRX, Hyundai Genesis, and FP turbochargers.
