Reason the MAF sensor is an issue is that this type of setup uses a heated wire in the intake air stream to measure air flow, the oil coats it and renders it useless. Suggested fix is replacement, not cleaning of the MAF. Hence manufacturers that use this system will not warranty your MAF if you use an oiled air filter, regardless of the amount of oil on it.

MAP sensor just measures intake vacuum and infers the air flow (real simplified explanation). That sensor never sees oil from the filter.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
