Hey there!
I was installing a K&N lifetime filter tonight and when I was replacing the Airbox screws one of them decided to snap, so now I'm stuck and don't know where to get a replacement. Any suggestions? I drive a 2007 Accord SE with a 2.4 K24a8 4cyl.

 

The honda dealership would be the easiest place. They can't be too expensive.

I put a bit of anti-seize on the threads when I install them, because I had the same thing happen. They get corroded in there.

 

Can I take the screws out and use like a zip-tie or something to hold it closed until I get a chance to get new screws?

 

If you have three working screws, then they should hold the top of the air box and make a seal on the air filter.

You can put a zip tie around it with the other bolts installed if you are really worried.
