    I've used brake clean on hundreds of cars including my own. As long as it's non-cloranated (sp?), you shouldn't have a problem. And don't hold it 3" from the nozzle.

    I've done this using non-chlorinaded brake cleaner. I really felt a difference after.

    you know, thats all i find in auto supply stores anyways... brake cleaner is great stuff... i love brake cleaner!

    im gonna go give this maf cleaner stuff a try though... especially since my car had a wacky boost behavior recently.
    Yes, that is me in my avatar! Kid's don't try this at home.

    i just bought that MAF cleaner and cleaned my air hog, needless to say the air filter was DIRTY! and the maf sensor was covered in black sludge and soot, i was amazed at how much junk was there! ive already cleaned and re installed the MAF, just waiting for the filter to dry to re-install that to see how much better it runs now.. it never really felt like it was a step slower or anything, but i guess ill find out soon

    If you happen to run a oiled filter- K&N, ITG etc- you absolutely need to be cleaning the MAF regularly- less so w/ a paper filter.
    Thanks.

    So you guys recommend taking the MAF off of the air box, disconnecting the wire connector...and then placing it in a bag of MAF cleaner. Shake it around and then let the MAF dry?

    Is there anything sensitive inside the black covering that shouldn't be wet? Drenching the whole thing is scaring me a little, but if everyone else is doing it with success...I guess I'll do it too.

    The MAF wire(s) are down in there.

    Be careful on the shaking part- these are very thin wires.

    I just used the plastic nozzle that came w/ CRC and give them a couple of gentle shots into the tube- let it dry and put it back

    I heard not to touch the MAF sensor with your bare skin. That can damage it. It looks like a little lightbulb inside a plastic circle.

    Wait, I thought the easily visible bulb is the "air temp sensor" and the thin filaments inside the black tube is the MAF sensor.
