I was sceptical at first but with the quest of running cooler in warmer summer temps, I decided to try some.
I am almost anal about monitoring temperatures of just about everything so between using my infra red heat gun and various other temperature indicators have a pretty good idea of what is normal.
Temperatures have dropped by 15*F.
Of course, as soon as the car is stopped and idles for a while the temp goes back up 15*F but as soon as the airflow resumes, it drops back down.
This is very significant.
Has anyone else used this product
