The COBB Turbo Blanket is a must - have for Subaru EJ turbo engines from 2002 - 2021. It fits a wide range of models including the 2002 - 2014 WRX, 2004 - 2021 STI, 2004 - 2013 Forester XT, 2005 - 2009 Legacy GT, and 2005 - 2009 Outback XT. This turbo blanket insulates the turbine housing, which has many benefits. It stops the loss of useful exhaust energy, speeding up turbo RPM acceleration. This results in faster turbo spool and quicker access to peak torque. It also reduces heat soak on neighboring turbocharger parts. Key features include a direct fit for EJ Subarus, protection against heat soak for nearby components, improved turbo acceleration, a fragmentized fire - retardant volcanic rock outer layer rated for 1500°F direct heat and 1800°F radiant heat, internal insulation with high - temperature calcium magnesium silicate wool, an inner layer rated for 1800°F direct heat and 2300°F peak heat, intermediate installation effort, and an installation guide. By using this blanket, you can limit heat transfer to the engine bay, keep exhaust gases exiting faster due to lower density, extend the life of under - hood components, reduce intake temperatures, and enhance your car's response.
Using the COBB Turbo Blanket is easy. First, refer to the installation guide provided. It's an intermediate - level installation, so if you're not confident, you may want to get help from a professional. Once installed, your turbocharger will work more efficiently. Be careful not to touch the blanket when the engine is hot as it can cause burns. Also, avoid getting it wet as moisture can affect its insulation properties. For maintenance, periodically check for any signs of wear and tear, like fraying of the outer layer. If you notice any issues, replace the blanket promptly to keep your turbocharger and engine bay in top condition.
