The MAF has the rectangular box on top of it. You remove the pigtail then loosen the band clamps on each side. Then pull the intake tubing back to release the MAF. Get some CRC electrical cleaner and spray the screen down. Be careful not to touch the element and for christ's sake, DON'T remove the screen.

everyone i know removes the screen

The screen helps even the airflow out over the sensor. Removing it provides zero benefit and as I've seen documented across many forums, can cause more problems than it *may* solve. Until you're maxing out the intake limitations (around 400 hp) there's no benefit to modifying/upgrading the stock MAF.

I'll change my mind when someone proves it on a dyno.

one more thing...i posted this on another thread but never got an answer..could this have to do with the MAF sensor..........

what is this? when i am backing out at work and put it in drive and start turning i feel a little hesitation...could this be the cause of that...also could a dirty MAF sensor cause that too?

its not spark plugs as i recently changed these
as another user said it feels like im running over mini speed bumps.
