Turbo Blanket for T4 (Thermal Protection)This method of thermal protection commonly known as a turbo blanket is installed directly onto the exhaust housing of your turbo and provides very effective insulation. It is sized for most common T4 turbos.Thermal insulation has 2 major advantages :A cooler engine bay due to the drop in ambient heat giving reduced intake temperaturesImproved turbo performance due to the retention of heat within the exhaust housingThe thermal blanket is capable of withstanding up to 950°C and is supplied with necessary mounting hardware. To maximise turbo performance we recommend adding heat wrap to the manifold and elbow/downpipe to maximise performance.
