Universal T4 Turbo Blanket for Externally Wastegated Turbine Housing

Fits most all T4 externally wastegated turbine housings


Thermal Zero turbo blankets go above and beyond when it comes to heat tolerance and durability.  The inner layer of the turbo blanket can handle over 2500 degrees Fahrenheit of direct heat.  The blankets are made with high quality 1 inch thick 6 pound density ceramic insulation material and covered with a silicone based outer shell that is colored either Black, Red, Blue, Chrome, or Gray. Since vibration on a turbocharger is inevitable we have created a more durable design.  Our turbo blankets feature a knitted wire mesh inner layer that separates the insulation material from the turbocharger housing, greatly increasing durability and reducing breakdown.


Installing a Thermal Zero Turbo blanket will cut down up to 80% of direct heat emitted from your turbocharger.  In turn this will allow the turbo to spool faster and be more efficient.


*Do not use this blanket on a turbo system where the downpipe V band clamp is unprotected*  An uncovered V band clamp is a sharp heat source that can cut the black outer jacketing material.  Please use turbo blanket part number TZ32258-L


Not sure if this blanket will fit your turbo.  Check the known good fit turbo models below or measure your turbo and check the measurement picture above to verify it will be a good fit.
