Gearing up for a long trip, figured I would clean the MAF while I'm doing other maintenance.
First unplug the MAF then remove it. You can already see dust/dirt on it.
That's from wiping the part the part of the maf that goes inside the airbox
Dirt/oil buildup can be seen on the IAT
Back side of it is much cleaner...
Take some MAF cleaner and spray it all down
Spray inside where the two MAF elements are
After that use a clean cotton ear swab to gently clean it, you can see how dirty the swab is!
VERY CAREFULLY wipe down the inside
Spray it all down with MAF cleaner again and let it dry
One thing I noticed is the o ring expanded a bit and didn't fit into the airbox well. Either remove the o-ring first, or wait a for it to dry and shrink.
Install the sensor back into the airbox and leave it unplugged overnight to make sure it all dries out.
