Yes, a JB4 among other things. The 40whp/50wtq is a very noticeable difference in a car this small/light, like the difference between a WRX and STI. It just becomes a different class of vehicle - but a difference you can "turn off/on" depending on your needs/wants (or remove without a trace if you need to bring it into the dealership).

Like any vehicle, how long it lasts will ultimately come down to how you take care of it (abuse/neglect). Mazda was rated #1 in reliability for a few years in a row recently, and I think they are still towards the top now. I'm sure things like this will ultimately shorten the lifespan of the vehicle, but by how much I don't know (and again, will come down to how you treat the car).

But alas, no car lasts forever, nor do we live forever. Sometimes people are willing to trade some longevity for quality.
