I would like to know how often you clean your maf sensor. I usually do mine about once a month or so.

If you have a dry type air filter you wont need to clean it near as much.

Not true. Bone stock STI with 2000miles, still with stock filter - and the MAF sensor was filthy when I pulled it out to swap the intake.

It can be true when people buy K&N or other brand oiled filters and load them up with way too much oil. The MAF will get dirty very fast and the car will run like poop.

I try to do it somewhat regularly which I would say is about once quarterly.

FYI, CRC's "MAF Sensor Cleaner" product, at $5.99 a can, is 100% identical to their "QD Electronics Cleaner" at $3.99 a can.

brake clean for 1.69 a can ftw.

you should clean your maf before you get any kind of tune, and before / after doing mods to the car, and generally speaking once per oil change is enough to keep it clean and reading properly. (typically 3-4 mo)

check the ingredients on brakleen. It is definitely NOT the same and not very safe for the plastic and rubber on the maf sensor.

I just cleaned my MAF w/ brakekleen. I will agree it will eat plastic and swell rubber, thats why i didnt spray any on the o-ring. I think ill invest in some other type of cleaning solution though.

Carb cleaner eats plastic and rubber. Brakeclean is safe for plastics. Ask a mechanic.

just fyi - if you do mess up that little o-ring, replacements are hard to find. i had to resort to using a completely different o-ring and "making it fit"

What other o-rings can be used? I have one that is nicked and needs to be replaced. Don't want to buy a new MAF if I don't have to.

Ahem....120k miles. Never cleaned. But I'm REALLY PISSED that I paid $450 to YIMI SPORT in Santa Clarita for a "dyno-tune" and they did NOT check/clean this first!!! ARRGGHHHHH!!! (I told them the air filter was okay...OEM). I will call and ask them if a re-tune is the proper thing to do. (Yeah, they'll probably say nope!) They only got me +6 hp, but I think +10 ft.lbs. of torque on a stock set up.

Every 3000 miles or less. Something so simple shouldn't be overlooked.

not if you do it correctly.

which means:
-carefully remove it from the intake
-spray cleaner onto the IAT probe (the part you can see that looks like a tiny kernel of red corn)
-spray cleaner indirectly up into the hollow of the tube to clean the heater wires. You should avoid blasting the heater wires directly, as it could damage them somehow.
-let air dry
-carefully replace MAF, beign sure to get it pointed the correct direction (plug in front, not in back)
-reset ECU to clear out the AF Learned trims

+1^^^^


and im really surprised that 'most' people that have polled do not clean their MAF. I guess as a Ford tech, and seeing how many engines have been DESTROYED by faulty MAF sensors...I am over cautious.

BTW, by DESTROYED, it has ALWAYS been from an engine running lean. 'usually' from dirty air filters (lack of maintenance by the customer) and/or oil bath filters.

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.
