Type I

Origin’s traditional drop-vent style bonnet allows air to flow through the radiator/FMIC, aiding in proper cooling during race conditions. In addition to greater cooling, origin FRP bonnets are much lighter than stock items.

Type II

Origin’s latest style vented bonnet, like the Type I, aids in cooling during hard driving by allowing free airflow through the radiator/FMIC and engine bay. Available in FRP, this bonnet has both vents at the rear as well as three fin-style ducts at the back of the motor area.
