SPF has both side naturally flowing (no fans) vents included in the roller and I find them useful. The allow air from the front vents to flow to the passenger compartment. When it is warm, I open the vents and cooler air flows through the foot compartments. I don't know that I have been in my Cobra with the ambient air temp over 85F, so probably not so cool when it is above 85F! No, they are not worth $1k, but they are really nice to have. For others trying to cool their passenger compartment, the heat shields inside the engine compartment are the most effective way to dissipate the engine heat. Check out the SPF heat shields. I normally feel zero engine heat inside the passenger compartment.
