This guy has been honest with, I guess, everything he said (some things he said were verifiable).
So how much do these aftermarket grilles impact airflow/cooling? 5%? 10%? 20%? Thank you.
It wouldn't matter... I had severe damage on my 911 TTS... weeks after I got it, and it was a 2k repair, from a stone that hit my AC rad. I installed grills and engine temps never increased. People I know who've added the same mod and who track their 911's, see no increase in temps either. I seriously doubt you'd feel any negative impact with these grills, but not having them will one day, cost you a rad.
