I know the old corvette's did this....however...as a Ford tech i can tell you they did not. so, not all cars do. Im not sure if suby's do it....but i doubt they do.

I do this once or twice a year, I should really do it every oil change though.

I cleaned mine a couple weeks ago..very dirty.

Not that cleaning these things off once in a while (especially if you use an oiled filter) is a bad idea, but has anyone ever really solved a problem by doing it? I just can't recall reading where someone sprayed the unit, and then said 'eureka, my car was transformed' or 'my idling problem immediately went away.'

just cleaned my MAF and now I get to re-tune my fuel map because of how dirty it was. Looked like it had a hairball on the maf sensor wires.

On my '05 (and probably most/all of the others) it's impossible to put the MAF sensor in backwards. The body of the MAF is closer to one screw than it is the other.

Stupid question here, but how long should I let it dry before I put it back in the car?

Also, if I'm using specific MAF Cleaner do I need to take off the o-ring?

A couple minutes tops. About enough time for you to put it back in the car and start the car up.

It never hurts to pull off the o-ring. But be carefull. It can swell and not seal and cause you headaches.

I cleaned mine every 4rth oil change or about every 12-15k on my old cars. My car just broke the 12k mark and I was running an oiled filter (SPT for 6k) so when I get home Im going to clean mine for sure!
Yes the SPT filter is oiled. Mine had oil in the bag and was so covered in it I had to clean it 2 times before it would stay on the intake!

I bet its nasty.
Ill take pics and such if any one wants.

Later.

Ok, so I just did it! Regardless that it's 22 degrees out.

I should mention that KN filter was on car for about a year, and sensor was never cleaned.

Steps:
Soaked sensor in rubbing alcohol (50%) for 15 mins.
Cleaned it with Q tips - very carefully of course, do not bend heating... thing. It looks fragile.
Do not attempt to clean actual MAF wires inside sensor, since they are even smaller and more fragile.
Sprayed it with electrical connectors cleaner, just to make sure everything is clean.
I dried it using compressed air(can), and then let it sit on the table for another 15 mins.

Pictures:

Dirty side (facing air filter) before:



Clean side (facing turbo) before:

Dirty side after cleaning:
