I noticed it was broken off after the check engine light came on and I looked the engine over. The previous owner or dealer that sold it to me must have glued it back on because I found glue residue on the tube side, looked like superglue

the nipple was gone... . I wouldn't be surprised if it was the dealer, the car was pretty messed up when I bought it, crushed panels form lifting, top not working and a couple more things, couldn't beat the price though

.
I was lucky to find a used airbox and tube on ebay, bought it together with a dejon cai, I need to get an airfilter for the cai, but I'm not sure if I want to put the cai on or not.
Anyways now I have a spare airbox.
