Turbo bags have numerous benefits for performance street/strip turbocharged vehicles, the most important being the reduction of under bonnet temperatures, and the protection of parts surrounding the exhaust housing. They also benefit by keeping heat inside the turbine housing, which allows the turbocharger to come onto boost a little quicker.
