Carbon Fiber Universal Hood Vents Excessive heat can cause major and expensive damage to critical components in a car. Engine bays, radiators, brakes, transmissions, and differentials all need good air flow to help transfer away unwanted heat. APR Hood Vents help extract heat and reduce underhood pressure from the engine bay. By creating an outlet for hot air to be released, high velocity airflow can enter the engine bay to create a effective cooling system.

NACA Duct Type 1 NACA-020825 NACA Duct Type 2 NACA-032026 Carbon Fiber Fender Vents Turbulent and high-pressure air has a tendency to build-up in the wheel-wells. APR Fender Vents help to reduce the air pressure by providing an easy path for the air to escape. The air flow just outside the vents is fast-moving and low-pressure, and the APR Fender Vents provide an easy path for the turbulent wheel-well air to leave as smoothly as possible 2010-up Mustang CF-214012 Universal Hood Vents Narrow CF-100002 Universal Hood Vents Wide CF-100004
