Cleaning MAF Sensor

Hey guys so I'm trying to clean my mass airflow sensors and can't seem to locate them. Any suggestions? I've looked it up and can't seem to find pics. I have stillen gen 3 intake btw. This is all I could find and I'm pretty sure they aren't them. Thanks

Yup, those are the mass air flow sensors.

Really? So should I just give them a soak with the MAF cleaner?

DO NOT touch the filament. Spray it from both sides with CRC MAF cleaner. Let them air dry completely. Put them back in. Done.

The bottle of MAF cleaner says it adds 4-10 whp, so I don't think I'd notice it even if it were true.

I do not understand why people want to fix something if it is not broken. I have driven cars 100K+ without ever cleaning the MAF. The car will let you know when there is a problem. YMMV.

Mechanic told me it could use a cleaning. That is why I cleaned it. Never said it was broken or I was trying to fix it

What I mean is; does it idle rougher than when new, has the fuel mileage gone down, does it hesitate or act rough when accelerating or other symptoms? If not, leave it alone.

^^^ Not to come off rude, but I disagree. Preventative maintanence is a good thing. If you take care of and clean things, there's less of a chance for something to go wrong.

No, but it won't hurt if you do.
