Noticed funny behavior of stock UL's airbags.
I noticed the car sit a lot higher in the day time and a lot lower at night or in the morning.
Then I realized it must be due to the temperature differences.
Air volume/pressure expend when hot and contract when cold.
Last weekend when it was 100 degrees out in the middle of the day, the car sit 1/2 inch higher then normal. These few days when it is cold at night, the car sit very low.
I bet you for some people who think their airbags are leaking when it sit in the garage overnight, they are not leaking, it just got cold overnight.
Air pressure in the tire does it too, they are a few psi differences between being hot out or cold out.

That's why for tires, you can get nitrogen fill. Much less fluctuation in hot or cold and the molecule size suppose leak out less over time. Wonder if we can get our UL airbags filled with nitrogen
