During the really hot parts of the year, C4 owners have air conditioning to keep them cool. What about spring and early summer, when you may want a breeze from the outside rather than cold air blowing out the hvac? Coupe drivers can always unbolt and take off the roof, but to me, that’s a pain in the butt. All I want is a little cool air, not a lot of sun and the top taking up all the room in the back.
The solution is Eckler’s Ventmaster kit (p/n 30728). This device fits ’84-’96 Corvettes and allows you to drive with the rear hatch cracked about an inch-and-a-half. The effect on interior ventilation is amazing. Interior temperature can be lowered by as much as 10°. No modifications are required to install this device. When you are ready for a little more air flow in the interior, simply pop the hatch, slip on the Ventmaster‘s hatch light and lock striker extensions, then close the hatch. What a cool little doodad! In the spring and summer, I use the Ventmaster all the time. I can’t imagine a C4 Coupe owner without one.
