People are saying this because flat-4 motors are not anything like an I-6. The EJ and FA engines are the same shape, and they have the same firing order. The balance works the same, despite minor differences in weight, because those differences are balanced against each other internally.
The intake would be much more likely to waste a motor in short order. Although I don't see it causing oil to drip out the bottom unless you're just ignoring what the car is screaming.

Balance has little to do with the failure causes. An L6 is naturally balanced. The problem is resonance which is affected by all the noted differences between the FA and the EJ. True that short crank H4's will have different frequencies than long crank L6, but there are still differences between motors.
However I'm not saying that it is the cause.
What I'm saying is that people dismissing it because the same part worked on a different motor need to rethink their logic. Perrin also sells 22mm rear sway bars for the BRZ which are clearly re-purposed WRX rear bars.
Now if those bars cause a handling related crash on a BRZ does logic say since they work fine on a WRX, they were not the cause (besides this hypothetical tuner's ignorance) of dangerous handling on the BRZ?
