It's a good addition to the stock turbo. Not 100% sure, but it feels like the turbo spools I tiny bit faster after putting this on. I do wish I could put the heat shield on top of this because I can feel the heat more now without the factory heat shield. No heat issues to affect performance though. I might try and make a hole for at least one bolt to hold the factory heat shield.
With an outer layer made from actual pulverized volcanic lava rock (continuous-filament basalt) formed into fabric and woven into a tight mesh weave, these turbo blankets are internally insulated with high temperature calcium magnesium silicate wool overlaid with a high temperature stainless steel mesh for increased durability and improved thermal resistance. The Lava Turbo Blankets are designed to withstand the harshest of conditions.
