Mishimoto 07-11 BMW N54 (135i, 335i, 535i) Turbo Blanket

If you're working on a 2007-2011 BMW with the N54 engine, like a 135i, 335i, or 535i, this Mishimoto turbo blanket is a solid option for managing underhood heat. Turbochargers get incredibly hot, and that heat can easily transfer to other parts in the engine bay, potentially affecting intake air temperatures and robbing your engine of power. This blanket is designed to keep that heat contained on the hot side of the turbo.

The construction here is pretty robust. It's got an outer layer made from volcanic lava rock and titanium woven fabric, which is tough stuff. Inside, a high-silica fabric works with a stainless-steel mesh to trap heat. The inner layer can handle temperatures over 2,300°F, and the outer layer is good for over 1,760°F. This means it does a good job of keeping the intense turbo heat from spreading out into the rest of your engine compartment, which also helps keep the exhaust gases hotter for a more efficient turbo that spools up quicker.

This Mishimoto turbo blanket is a direct fit for the stock turbochargers found on many N54 BMWs. It's backed by Mishimoto's Lifetime Warranty, so you can install it with confidence knowing it's built to last.
