Air filter,primary and secondary

[RedRide]

......Oh, and in a recent magazine (MotorAge?...can't really remember) they had an article on MAF meters and oiled elements. I noticed their claim that many automakers will not honor warranties if oiled filter is installed.

This just illustrates the misinformaton out there as Toyota sells an oiled filter. So, how can they not honer a warrenty?
We all know how some dealers tend to not want to honor warrenties and look for excuses.

There has never been a doumented case where an oiled filter caused a MAFS to fail.
The worst case senerio can be where a filter is over oiled. Even then it can be cleaned.
A dirty MAFS does not equel a "failed" MAFS.

A MAF can fail for various reasons and just because an oiled filter is installed, does no mean the filter is at fault.
