Hi to everiibody,
I would like to tell you my story about K& N and may be save some MAF......
I have a CLK 430 since 2 years with 180.000Km now , 7 months ago I decided to put K&N filter because i was doing maintenance and i had to change MB filters.
Aftre installing these i was thinking to have more power in particular at low RPM but may be waspalcebo effect..........but after a while i had code P173 and p170 and car start tu run bad at idle and loose power at high RPM.
I tried to clen MAF with alcool and with special product to clean electronics, dry with soft compressed air..........but no result...
So i cnahged MAF and put new MB filters and the car i beck to normal.
This just to say you that for me this kind of filters are not working with car wich MAF like this.
I hope thse can save some owner to buy expensive MAF.
Many thanks guys.
Alberto
