The COBB turbo blanket is a perfect way to keep temps low in your Subaru WRX STI's engine bay. The blanket easily fits over your stock turbo and still allows for a bigger downpipe to fit as well. These COBB turbo blankets are made from a fragmentized fire retardant volcanic rock outer layer and internally insulted with high-temperature calcium magnesium silicate wool. The outer layer can handle up to 1500 degrees Fahrenheit of direct heat and the inner insulation can candle up to 1800 degrees Fahrenheit of direct contact!

Key Features:

• Very high heat resistance (1500 degrees F of direct heat, 1800 degrees F of direct contact).
• Direct fit to the stock or similar sized turbo.
• Helps with turbo acceleration / spool.
• Still allows you to use a larger downpipe as well.
• Helps significantly lower temps in the engine bay.
