How often do people clean they maf or at all ??? I had noticed my 3.5 e50 was just a little sluggish off the mark compared to what it should be, not slow just not as quick as it used to be ,I thought top end hadn’t changed at all , my mpg had gone up slightly, prob down to me not booting it in winter , so I decided to clean maf first , I couldn’t believe difference in car , it’s like a bullet off the mark again and top end is quicker on pick up , pulls much better , so it’s well worth the 12 quid or so I paid for tin to do it , only down side my mpg well prob drop down due to my foot ha ha

I’ve just done mine and couldn’t believe how dirty it was. I’ve not been out in it yet but I’m hoping It will make a difference. Now I know how easy it is I will probably check it quite regularly.

Just spray it on and wait till it drys
Just as Malcolm says. By all means give the MAFF housing and guaze air intake grill a good clean along with the rest of the MAFF body but just don't touch the MAFF element. Spray on and leave it to do its own thing.
