Some one is bound to jump in and claim that the MAF was contaminated by the K&N filter oil or from dust getting past it (groan). Some dealers would be happy to refuse the warranty because of the K&N. We have seen such things reported here before.
Some vehicles can contaminate a MAF after engine shut down with PCV vapors drifting in.
If someone wants to clean a MAF, plastics safe electronic cleaner can be used and it must no have any residuals in it such as the ones designed to lubricate volume controls and such.
MAFs do fail, I think that many forgot about this with the span of T5 production that did not have these. Saab apparently left themselves with engines at risk with MAFs that drift off-spec. Probably something that could be managed properly/better in the ECU software.
MAF failures in the 1980's were massive. VW had a lot of MAF failures a few years back. A complete MAF failure is not a danger to the engine.
