Default aftermarket air lid fit?

I recently installed a whisper air lid on my 99 Z and it keeps popping the metal clips off in the front and appears to not fit well at all. Anyone else have the same issue and found a way to resolve it or does anyone know of any other aftermarket air lids that seems to fit better? thanks.

The last time I saw that, the back of the lid wasn't seated properly. Are you sure the filter and lid are in the right way?

yes it is definately seated properly and the filter is in correct. it almost appears that it is being pushed forward to much by the intake hose.

Classic install error. The front of the lid needs to be down in the groove in the lower airbox. Notice the area between the clips in the picture below:

pull the lower box out a bit and where the lid is between the clips put it down a bit and the lower air box will help keep it on. I have done this for 2 years and the clips have never came off, and it was installed correctly.

Try taking everything off up to the TB and putting it back on, making sure everything is as snug as possible. What bellows do you have? Maybe you could try trimming it a little bit if it's an aftermarket one.

I cut a big notch out of the lower airbox assembly under where the MAF rests. You also have to insure that that airlid is pushed all the way towards the intake and that the front edge of the airlid is behind the lower front edge of the lower airbox. It will clip on so tight you'll worry about popping the clips back off. I had the same exact battle, but once I had it pushed all the way back and that front edge behind the lower box lip, all is good.

i have been told that the slp lid simply hits the hood. i have not heard of that problem with other lids but there may be problems with others as well.

As stated, make sure all 4 "prongs" are in the holders at the back of the lid. Don't be afraid to push down and back a little on your lid to get them all in. Once they are in, the lip of the lid that is BETWEEN the two metal clips has to be BEHIND the airbox.



Outside the clips is fine to hang over, but inside the clips the lid has to be behind the airbox lip.

My old SLP hit my hood. The pic above illustrates exactly how I installed mine. You feel you dogged down a weathertight hatch for condition Zebra.
