The Perrin downpipe thermal blanket fits snugly around the upper portion of your downpipe to keep nearly all radiant heat away from your intercooler, intake and other engine components and in the exhaust for a faster spooling turbo. As exhaust gases cool down they loose energy and velocity. The thermal blanket keeps hot exhaust gases hot, which in turn keeps the velocity of exhaust gases high, improving response while decreasing underhood temps.
The thermal blanket features 3 layers of construction: an outer cover made from silicone impregnated fiberglass, an inner layer made of calcium magnesium silicate insulation, and stainless steel mesh used to contain the inner layer. Stainless steel rivets are mounted to the blanket and stainless steel wire is supplied to secure the blanket to your turbo making installation a breeze.
Fitment is designed for aftermarket downpipes. This will fit loosely on stock downpipes.
Does not fit rotated downpipes.
