Q: I unknowingly drove my car for the last 5,000 miles without an air filter, what potential damage has been done?

我确实相信不会造成严重损害。制造空气过滤器是为了防止任何叶子或其他碎屑进入发动机。但是，由于许多较新的进气系统的设计，碎片可能不会那么远。这是由于屏幕内置在某些节气门体内。我建议您使用进气/燃料系统清洁以及另一个oil change. Once all of these maintenance items are completed, the vehicle should be good to go with no damage to worry about.
