Laser cut louver panels to fit on top of the engine cover humps.

Heat rises.  In the engine bay the highest point are the humps in the engine cover which capture the air like a nice parachute.  These vents allow hot air to escape out the back both at speed and when sitting still.

Parts will ship flat and be quoted based on buyers zip code.  Typically around $12

Combine with other louvers and save $5.
