Have you ever wondered what the fabric under the hood of your car was used for? Well you have come to the right place! In this video I run a set of tests both with and without the hood insulation installed. I am testing on the basis that the insulation limits sound and contains heat. This test is done on a 2000 Mustang GT so results may vary depending on the car. I hope you enjoyed this video if you did please share with someone else who may also find it interesting.
