Zero dark

It's a 2015 though. That wouldn't even have crossed my mind. A failed O2 would decrease that much power?

Tuner suggest possible takeda cold air intakes rubbing against the crash bar or bumper that that is severely decreasing air flow.

That sounds like an excuse to me. I have them and there are over 2 years old. The only part the could "rub" is rubber :/
