I have seen posts of some guys having a hard time getting the MAF plug off.
The MAF (mass air flow) plug that is on the driver side of the air filter box can be dificult to remove unless you find out just where to squeeze the release clip.


1.) First pull back the little gray retainer locking clip with a small screw driver.
Be carefull not to pull it all the way off , it should stay clipped to the plug.




2.) this shows where you have to put your finger tip underneath the plug.




3.) then squeeze the release clip as you pull the plug off, it should slide right off with no resistance once the release clip is squeezed.





4.)this shows the plug removed and upside down so you can see where your finger tip has to push on the release clip.
When you get the plug off turn it upside down and take a close look at the release clip and you can see how it holds the plug in place and how you have to depress the clip so it comes off.





5.To replace just push it back on till it snaps on then push back in the little gray locking clip.





6.) When you have the air filter box off it is a good idea to take the rubber pads out of the air intake box. Otherwise they can come loose and get sucked down the intake.

Thanks for the heads up, I keep thinking there must have been a better way for GM to design the location of the pads, were they in the air box on the C5 ?

I hope that little grey clip isn't essential. Mine disintegrated in my fingers when I removed it. Pretty fragile.

Maxx thank you, that made my day. Good info.

Great write up.

Say, I thought those hydrocarbon things were rodent traps if they crawled into the intake!

Thanks for the pics for sure!

Two questions though: Your thoughts/comment would be appreciated.

I don't have the KB yet either, so can't address that part of your question, but as for the first part, those pads are not there to absorb oil in the first place. They are intended to absorb hydrocarbon gasses from the engine after it is shut down. That's supposed to help keep our air cleaner. When the engine burps oil due to overfill or whatever, it loosens the the pads and also probably destroys their ability to perform their intended function when they are oil-soaked.

Aside from the rodent application, the H/C pads are for PCV gas absorbtion. However agressive cornering causes oil to be sucked out to there, so a catch can is needed. Overall, the hazards of keeping them outweigh pollution considerations. Unless you consider the waste associated with engine repair a pollution problem.

The PCV system routing, as with most EPA required applications, has considerable problems, topic addressed in other threads.

It appears the PCV hose is just repositioning for appearance, not function.

Maxx,

Great write-up, just what I was looking for to take the grey retainer off.

Thanks,

This post and pics were a great supplement to Jim's video!

Thanks very much Maxx!

I know I'm digging this one up from the dead, but I just found the thread after searching through Google looking for a walkthrough just like this and it was really helpful. I just cleaned out the MAF sensor on my '07 Z06 with electronics cleaner spray while cleaning out my throttle body.

Wow, just short of 5 years.
