NO!!!! The BumpSkid does not raise the operating temperature on the RT or RS. The extra lip around the leading edges increases the flow of air into the radiators.
There was a discussion about the ambient temp gauge showing a higher temp after installing the BumpSkid, but when I have investigated this with over 10 different RT 's I still haven't found one registering a higher room temp.
Hundreds of satisfied customers with no increases in operating temps.
