But I mean, how much cleaner are we talking here? A tuned engine might run a bit better, but idk if it actually puts a dent in air pollution. Maybe it's just me, but cars are still a huge problem overall. This seems like a drop in the bucket compared to bigger issues. Just feels like we're patting ourselves on the back for something minor.
Totally get that, it can feel small scale. Honestly, just keeping my own car's filters and sensors clean made a way bigger difference for me than any performance tweak ever did.
