Any relation between RENNTech intake and mass-airflow sensor?
The dealer replaced the mass-airflow sensor for the second time on my car and are claiming that it is caused by the RENNTech air intake. They are also saying that if I have another problem with it then MB will not pay for the MAFS a third time because of aftermarket parts. Any truth to this or are they just trying to fool me?
Thanks

If you are implying that a change of AIR FILTER may cause the problem then say so, along with your reasoning.

Check this link here The only issue with airfilters is that it is possible for a less restrictive air filter that lets larger particles through, to contaminate the filament on the MAS. Not all high performance filters do this though, so it cannot be used as a broad excuse. Secondly the filament is both shielded from direct debris and will also burn most pollutants off. I am not saying that it is not possible for the airfilter to negatively effect the MAS, just that it is very unlikely and only in the event that the airfilter used provides poor particle filtration. It is not possible for the Renntech airbox itself to cause this fault .
I would be interested to see arguments to the contrary.

Thanks for the info!
My concern is that fact that my car still shakes a little when I come to a stop, especially when I first start the car and the engine is still cold. Could it be possible that the dealer installed a faulty MAF again? The last one they installed only lasted about 500 miles until the car lost most of its power and eventually the check engine light came on and the car would hardly be able to accelerate and kept stalling.
