Quick question:

Last week I got a CEL on my 2016 ST2. I took it up to the dealership as soon as possible and they found the code indicated a faulty O2 sensor. Before I took my car up, I removed the Green Air filter and put the stock on back in (just in case). My question is, would the Green Air Filter be of any cause for this CEL? I want to be sure this wasn't the culprit before I re-install it.
