I finally did this and it worked well. My inserts are a little delicate, but they seem more durable than the plastic threads and oem screws. I used titanium hardware for extra bling and lightness.

That looks great! I recently changed air filters and my threads are still holding tight.

i've had my airbox out probably about ten times for various tasks since i did this. i just started to have some minor issues. one of the anchors broke and fell out, and i have another one that is coming loose during fastening and the bolt is pulling it up out of the seat before it gets tight. i just have to press downward as i'm tightening it to encourage the anchor to bite.
other than that, the lower airbox is holding up well.

I had an issue where a shop over torqued the screws and pulled out the inserts. Bought a set that gets pressed in from the back. There is one position in the back where the brass lip needs to be filed a bit.

I did mine with some random inserts and machines screws I found at Ace hardware. I dapped a bit of JB Weld on the inserts before installation and the ones that didn't blow out hold on pretty tight. I plan on doing it again within the proper sized inserts when I come across a cheap air box.

Updated initial post to include info on inserts that install from the back.

Reviving because I found this super helpful. Used the McMaster Carr inserts that drrust linked (first post) which install from the back and they worked perfectly with the 7/32 bit. Used a longer steel screw to pull the insert into place.

Saved me from having to purchase an entire new airbox to replace one that was otherwise completely undamanged, so a total win.

Thanks for your review. What is the length of M4 screw you bought and where did you get M4 screw from?

I just ran down to Ace Hardware for screws (they generally have a great selection of metric hardware) and tried 25mm, 30mm, and 35mm and like drrust found that the M4x30 seems to be the ideal length. I used a 40mm length screw to set the inserts in place.

I am going to swap them out with these titanium ones - for looks more than anything:

and will update when I get them.
