Well first trip with under tray only showed a little as winds are at least 20 mph out today. I need to tape it better. There is tape blowing under my car.
But, it did keep my water temp much higher. It actually peaked at 217. But kept steady around 206. Which is operating temperature in the summer. It even stayed that high with heat full blast.
Before I was lucky if it hit 180 and with any heat on it would drop to 130.
Tygen. Do you know what acceptable temperature ranges for the zx2 are?
