2005-2009 Mustangs have a lot of power behind the wheel and that power comes from under the hood. Hoods are added to perform certain tasks to optimize performance. BMC Extreme Customs has a good selection of 2005-2009 Mustang hoods to help your car run at its peak performance running better than ever. Upgrading your stock hood to a custom one is a major change to the exterior of your car and is a great way to maximize engine cooling and heat extraction while changing the appearance of your car. Many options offer heat extractors as vents running down the middle or just off-center on both sides, but the various cowl hoods work to let the engine breathe more easily while driving.
