M113 V8 Mass Air Flow Sensor

Fits most M113 V8 Mercedes from 2000 to 2006 included the S500, E500, and SL500. If this part fails, you will get a check engine light and a specific P code. If it is just underperforming, you may get excessive rich or lean mixtures, leading to loss of power and poor fuel economy. Try cleaning it first or if over 100,000 miles just replace it.  272273
