Can gear be exposed to high temperatures (90-130 degrees F) for a week or so and still be ok? As in, in the trunk of a car for a week? (hot in the day and warm at night)

I may have to leave my gear locked up in the trunk of my car because my girlfriend will be at my place while i'm out of town and she doesn't know i'm on cycle, i'd like to keep it that way.

Thanks
