Yup. INLINE 4. Whupps. Fixed.

 

Ratchet strap, exhaust / BIG zip ties, make your own hole.

Pictures help.

 

Salvage yard and get a new box. Or just say f**k it and add a k and n filter setup

 

These over-center clamps are very similar to the OEM clamps used on other vehicles.

 

HVAC metal strap. Bolt, nut, and a butterfly nut. Those straps have holes already. Cut the strap short of full circle. Put a bolt in with nut on one side. On the other use butterfly nut, tighten enough. This is almost like variation of how the water heater is strapped in.

 

I'd use extra mayo.

I endorse all these solutions people have advised. Replacement clips/clasps,hasks, or ratchet strap, keep it closed and unable to open. Just gotta deal with the slightly more work to inspect/replace air filter. Yea, I'd rather do that than replacing the assembly if cost $$. Make sure no other holes/cracks (even hairline) on assembly as that will impact fuel economy as well as potential CEL. But if it's "sealed" with whatever apparatus you rig up, and safe from any potential unraveling or vibrating free, I'd say go for it.

 

There like 10 or 15 from a pick a part for the box

 

Thank you for the great ideas!

1) Here is the very temporary clamp (zip ties) so I could go get the supplies.
2) The snapped screw
3) Bill of materials for aftermarket performance clamp upgrade (wing nut is OVERSIZE versus the bolt)
4) Assembled clamp upgrade!

Will try it out tomorrow.

 

Drill out the bad bolt/nut.

Carriage bolt up from the bottom - washer-nut (Airbox) washer - nut or wing nut.

You should only have to remove it every 30,000 miles or so.

 

Aha, pics help. A slot would work out. No need to make it deep, just enough that you can insert a #1 flat head bit or screwdriver. Spray wd-40 or put drops of ATF. Then hold the bottom with one hand and then press-turn. Sometimes counter intuitive but if CCW turns hard, first some CW then CCW. Then other side. At least you can restore one side at a time.

Also that bolt head looks like little bit sticking up. If yes, small needle nose vice grip may work too? Just thinking out loud.

If the bottom half can come off (i.e. removing cleaner assembly from car), I wonder if one can just flip it upside down to be able to access protruding threads underneath via needle-nose or locking pliers and penetrating oil?--kinda like how you said. I would think that there would be more material to hopefully grip with if that bolt went far enough below vs top side.

 

Your zip ties are good enough for me. I just tape it using 3M Duct Tapes for five years with 0 issue.
