Looking for two 12mm bolts to fix my Air Box to the inner wing... help!?

 

I have a huge box full of impreza bolts, any idea roughly how long a bolt you need?

 

Not sure mate, my wagon came with a K&N which I replaced with an ebay Air Box, but they didn't send the bolts. I'd guess they don't need to be long though, say an inch or two?

Very kind of you to help though, appreciate it.

 

No problem mate, pm me your address and I'll have a wee look and I'll send some out to you
