I know ETI is slightly different with the "Nismo" variation. I know they were able to improve the performance of them over the normal 370Z ones. ETI is fine after tuning, as it's really just a programmed adjustment for the larger diameter tubes so the sensors read it a bit better. I didn't have issues with mine at all. I drove in the rain, the heat, trip to Magic Mountain, they worked 100% fine. I think Seb doesn't like them because the ETI is already making some adjustments and he has to work with it as opposed to other intakes where he just tunes. Thing is, a lot of other intakes neck down at the MAF to trick the sensor, but it doesn't make sense because it's introducing a restriction anyways. If you were to swap, I would get AAM's as they have worked around it with a removable sleeve at the maf.
