I had the concern about how the bug screen would effect the temp of the coolant and transmission (I have gauges for both). With ambient temps on our trip in the mid to upper 80s, I couldn't tell a difference from the temps before I installed it. I agree, with bugs (and they were on the raditor) it could have been no different. My thoughts before purchasing the screen was if it raised the tips too much I cauldron easily remove it. Instead, each morning before taking off, I just used. Red rag to remove the dead ones. I have no regrets on purchasing and using it.
