I haven't spent a summer with the KKM on yet, but if I notice a loss in power due to heat, I will buy one. I think $75 bucks isn't that much for the benefit. I live near Boston and rarely get on the highway so underhood temps around the city could kill my performance. If I mostly drove highway and didn't have $75 bucks to part with, I'd probably skip it. But either way I think it is well made and conceived and I hope they make a profit as a reward for their hard work and dedication to expanding our options.
