This is a universal turbo blanket designed to cover the exhaust housing of turbochargers with big T4 turbine housings, .96A/R and up. This will easily fit on all T4 housings (even the big divided ones), but the next size down would be ideal for fitment on T4 housings .96A/R and smaller. It keeps the heat contained within the housing and out of the engine bay. Don't melt the paint on your hood, ruin your radiator, or fill the engine bay with hot air. A turbo blanket also traps energy in the exhaust housing of the turbo making it more efficient by maintaining operating temp.
