Review on Mishimoto MMGRT 215 Heat Defense Protective by Adam Jackson

I was looking for something that would have a slightly cooler charge (pre-turbo) for my Focus ST and lower the temperature in the engine bay. I stumbled across this and definitely made the right purchase! Not only does this improve the look of the engine compartment, but it also reduces surface temperatures by 10-15*F at the expense of the turbocharger inlet and closer to the first bend after the filter, as well as reducing boost temperatures by 5-10*F. Compared to other Focus ST without heat tape on inlet just after autocross with digital temperature gauge.
