Why are you not using the remainder of your warranty???

It needs to be stiff enough to not sag over time like said, some cheaper filters can't do that.

Post 19 has multiple problems, no one fix there.

Post 18 says same issue but quotes 5 separate codes, highly unlikely unless wiring harness issues or a vacuum leak maybe.

Post 14 MAF sensor is absolutely under powertrain warranty, car will not run without it. Lying dealer there.
