Your Audi S4 is fast, no doubt about it. But what if you want to make it more efficient and resist damaging, power robbing heat around your turbo? One option is to install a turbo blanket. A turbo blanket helps to prevent heat from escaping from the turbocharger hot side, while keeping the cold side colder. This leads to faster spooling of the turbo and faster access to power and greater efficiency. It can also help to prolong the life of other engine bay components by protecting them from excessive heat generated by the turbo.

Installing a turbo blanket on your Audi S4 is not difficult, but there are a few things you need to know before you get started. First, make sure you have the correct blanket for your car. The Forge Motorsport blanket works when installed on the B9 Audi S4. Second, take care when installing the blanket around the turbocharger itself. You should use gloves to protect your hands and avoid snagging any PCV components. With a little care and attention, you'll be able to install your turbo blanket quickly and easily and enjoy the benefits of increased power and improved durability.

When installing this turbo blanket, the turbo does not have to be removed. A zip tie can work to pull the spring around the turbo, and it seems that one spring should be enough to hold it in place. If you run the factory heatshield, there is probably no reason to install both springs.
