If the filter oil was coming off in significant quantity, this would mean the MAF got dirtier quicker, no error there, and it would be annoying if it was really often, has anyone found this to be the case? |

in all honesty, how many people use full throttle that often? |

Had a run in with a 'professional mechanic' earlier this year, he was proud that he had done a good job fixing many cars by replacing the MAF and fitting a genuine air filter to prevent lint contamination. He had never attempted to clean one, the thought that he could do so and save his customers money had never entered his head. Even after it had been suggested he held fast to the fact that cleaning the MAF was not in the makers service book. |

I doubt he would parcel up the electronic contents of his scrap bin and send it me for re-con. |

Some alternative inlet arrangements , including alternative air cleaners and induction kits , as well as producing increased noise levels and potential icing problems when cold , can produce significant power loss. Cars that use by-pass type MAF sensors (e.g. many Fords , Nissans Jaguars etc.) , reley on the air-flow through them being reasonably laminar to meter correctly , indeed the engine's 'calibration' will take account of this. We have measured , for example on a Mondeo 2 Litre , a drop of 8 BHP in the mid range when a certain well known (and highly hyped up) make of air filter was fitted in place of the paper original.
